Tyson's Corner, Virginia, IAD

If you are a regular reader at Redgannet, you will know that at least once during every trip I do something daft to spoil the day and then try to blame either someone else or beer. If I am honest most of these incidents can be put down to simple stupidity.This month alone I have been stuck in soft sand, been diverted by a mountain on fire, been held up by horrible traffic, called from standby at a moment's notice, and last night I left my glasses in the bar and didn't get them back until nearly midday.

It was cold during the morning and I was pleased to see that it had warmed up by the time I managed to retrieve my spectacles and get out. I visited a thin ribbon of woodland that passes behind the malls at Tyson's Corner. A tarmac path leads off in both directions from the southern end of Westbranch Drive (Google Earth ref; 38 55' 31"N 77 13' 19"W), dead-ending one way and leading to a small pond the other.
I chose the south-easterly direction to start me off. American Robins were picking through the leaf litter. This individual was sporting the filoplumes much beloved of Jochen and Owler. A Carolina Wren called from a tangle. A small brown bird in the undergrowth caught my attention and shortly a Hermit Thrush came out onto the path, pumping its tail.
A small barrier at the dead end would not stop an intrepid explorer and a deer path continues past it. The White-tailed Deer were feeding in the scrub beyond the barrier, but spooked when they saw me. The group of about a dozen trotted with their tails high to the far side of the meadow and watched me from there.
I returned to the road, passing a pair of Downy Woodpeckers on the way. The path continues on the other side of Westbranch Road and heads north-west. I suspected that a Cooper's Hawk had a nest here after seeing him the day before, flying into an evergreen with a small stick in his beak while the female soared overhead. Sure enough, he was perched on a nearby branch that arched over the path and stayed very close to the evergreen when he flushed as I passed beneath.
Further on were some Carolina Chickadees, but also a couple that had a much slower call. This area is close to the overlap zone for Carolina and Black-capped Chickadees, but I hear that songs and calls are learned and are not a reliable way of distinguishing between the two species, so I shall stick with the Carolinas.
A Northern Mockingbird, on a rustic wall near the supermarket was the only bird all day that had sat still for a photograph.
The biggest surprise of the day came almost back at the hotel when a large raptor was seen overhead. I had been seeing a lot of Turkey Vultures and Red-tailed Hawks over the last couple of days, but this one caught my eye with a different flight style and silhouette.
It was a Bald Eagle, soaring over Tyson's Corner.

Great Falls Park, Virginia

The Potomac River marks the boundary between Virginia and Maryland. At Great Falls Park (Google Earth ref; 38 59' 49"N 77 15' 17W ), after draining some 11,500 square miles of its rainwater, the river surges through the narrow Potomac gorge and over the rapids for which the park is named, dropping 76 feet in the process. The flow was slightly above normal today and made an impressive sight. Viewpoints have been built to show off the falls at their best, but worryingly, a high water marker shows the levels of dramatic floods that covered these platforms when the river rose to inundate the picnic areas at the top of the bank.
To facilitate supply and trade with the western frontier, the Potowmack Company (founded by none other than George Washington) built a series of canals to navigate the falls. Remnants of one these canals from 1785, are still visible on the Virginia bank and continue to provide a calm water habitat alongside the torrent of the river.
Downstream from the viewpoints, the canal holds water and a rough harmony emanated from it. Frogs were calling and copulating in the sunshine. I watched for a while and loved the standing waves produced by the vibrations when this frog inflated his throat sac to call. Further downstream, signs request no cycling.
By the Visitor's Center an Eastern Bluebird was eyeing up a female who flew provocatively close to catch his attention.
Upstream of the main area a path follows the canal and arrives at the bank of the fast flowing Potomac.
Islands mid-river held some Canada Geese and on the far side a large nest looked to have a white head poking from it. I watched for a while but it didn't move. A ranger told me that it was the nest of a pair of Bald Eagles that return each year to breed, but no-one had seen the birds yet this year.
On the near bank a Great Blue Heron was keeping an eye out for fish. I must admit to being captivated by the river and did not venture very far into the woods away from the water.
The environment inland from the river is mature forest with a lot of dead wood. There were plenty of Red-headed Woodpeckers and a Pileated Woodpecker too. A Downy Woodpecker was heard, but that does not qualify it for the list.
White-breasted Nuthatches, Tufted Titmice and Carolina Chickadees were common in the woods. This area is very close to a point where chickadees could get tricky. These gave a much faster call using the "Mississippi River" rate of about 6 "-dees" per second following the "chic-a" instead of the slower, "Hudson flow" at just 3 "-dees" per second.

To cycle from Tyson's Corner, head north on International Drive. You will soon pass under the 267 Freeway and then cross an odd junction leading into Spring Hill Rd. After about 1.6kms you will reach a crossroads with a gas station. Turn west (left) onto Old Dominion Dr and follow this for 4.3kms. At the junction, Great Falls Park is sign posted immediately ahead and is about 1.7kms into the woods here.
The roads are well paved, but are a little narrow. The trails in the park by the river do not have a hard surface, but were easy to cycle on.
There is more uphill on the way back and it took me approx 45 minutes to return to Tyson's Corner.
There is no taxi rank here. If you wish to visit by taxi, you should arrange a return ride.

Birds seen; 22

Double-crested Cormorant 3, Great Blue Heron 2, Canada Goose 6, Turkey Vulture 12, Black Vulture 1, Cooper's Hawk 2, Red-shouldered Hawk 1, Red-tailed Hawk 3, Mourning Dove 7, Red-bellied Woodpecker 7, Pileated Woodpecker 1, Carolina Wren 2, Eastern Bluebird 3, American Robin 12, Carolina Chickadee 5, Tufted Titmouse 12, White-breasted Nuthatch 2, Blue Jay 4, American Crow 6,

Betty's Bay and Leopardskloof.

Surely this morning I would be able to go about my bird watching business without sinking into the sand or getting caught for hours in traffic. My destination was Sir Lowrie’s Pass in the Hottentot Holland Mountains. I wanted to look for Rock-jumpers and the like at the top of the pass and had made an early start. At 06.30, at the foot of the pass, a police roadblock was stopping traffic and diverting vehicles. The mountain was on fire!
 Leopardskloof at Harold Porter Botanical Gardens

After a quick change of plan, I decided to visit Betty’s Bay and Harold Porter Botanical Garden instead. I arrived too early for the gardens, but the small village at Betty’s Bay had plenty of birds, including the only other mainland penguin colony in Africa (the other being Boulders that I visited in the previous post). Cape Francolin were common around the roads of the village and the first Cape Weavers and Pied Kingfisher of the trip were found here too. The white, guano covered rocks were easily visible from the car park.
Down on the beach some Egyptian Geese sat on a small fence. Some Hartlaub’s Gulls and Great Crested Terns shared a breakwater with a Cape Cormorant. In the water was a Jackass Penguin. A sudden flurry announced the attack of a Peregrine Falcon as it swooped. It seemed to be aiming either for the cormorant or the penguin, but missed both and flew back to alight on the tall aerial to the right. It wasn’t possible to access the penguin boardwalk until 08.00, but 2 penguins, like naughty teenagers coming home late, found a way in via a shallow gap under the fence. A Cape Hyrax had come out onto the rocks to warm up in the early morning sun.
My hope was to visit Leopardskloof in Harold Porter Botanical Gardens and at 08.00, the gates opened and let me in. Leopardskloof was a fenced off area that needed permission and a key until recently, but now it is accessible to anyone during opening hours. It consists of a steep tract of coastal fynbos and a small section of coastal forest in a ravine with a stream running through and a waterfall at its head. The sides are precipitous and the rocks, though stable in the short-term, are plainly vulnerable over time.
To reach the kloof it is necessary to pass through the gardens to the top of the slope and cross the stream. Scum on the surface of the water under the bridge, had formed intricate patterns that could only have come from Africa.
The garden held Orange-breasted Sunbirds, Malachite Sunbirds and Some Alpine Swifts overhead.
A fire has taken much of the fynbos leading up to the ravine, but beyond the fence, all seems to be intact. A Sombre Bulbul called its strident alarm as soon as I came over a little rise.
 The trail leads into the forest and crosses the stream 3 times before reaching Steffina’s Gift. Small stones had been placed by a plaque dedicated to a benefactor who had sponsored a series of ladders that enabled access to the top of the ravine and the small waterfall. The top pool is surrounded on three sides by vertical cliffs and a lip of rock at my back made me feel as though I was in a well.
The climb up was not been arduous, but neither had it been productive. Only the bulbul and a couple of Cape White-eye had shown. I had stopped for a while after hearing what might have been the call of a Blue-mantled Crested Flycatcher but was not able to confirm it for a red tick. The way back down brought a Cape Batis, a couple of Olive Thrush and a few more white-eye. Leopardskloof had not lived up to the hype today, but it does have a good reputation and will be worth another look next time.
Back in the gardens a Familiar Chat flitted by, stopping only briefly. A pair of adult Verreaux’s Eagles were circling. They found some warm air, gained height fast and glided away, showing their distinctive silhouette.
Back at the penguin colony the boardwalk was busy I stopped to see if a pair of them would give a nice superimposed picture. It almost happened, but my main interest here was the cormorant roost at the point. Using the scope, I managed to pick out four species, Cape, White-breasted, Bank, and Crowned Cormorants. The first two species were easy to find close to the viewing spot. The other two preferred to be at the extreme edge of the point.
Out on the ocean, Cape Gannets approached a little closer to shore, but were still quite distant. They formed rafts when they weren’t fishing. On my way back to the car I added Sandwich Tern and White-throated Swallow, but the highlight of the day came in the shape of a Kittlitz’s Plover.
The little bird had scraped a little nest right beside the busy path that visitors use to access the penguin boardwalk and had to retreat from it whenever anyone passed. I stopped in the middle of the path and placed my bag strategically so that path users would have to use the far side of the path and not disturb the plover. This partly worked except that some people will still insist on walking in front of cameras, even if they have to step over bags to do it. More considerate people stopped to see what they might be disturbing before making a wider pass.
Its (his?) choice of site is surely a bad one and although there was a potential partner on the beach, it never showed any interest in a nest so subject to disturbance.
Betty’s Bay is on the coastal road between Gordon’s Bay and Hermanus (Google Earth ref; 34 22’22”S 18 53’ 38”E. The white guano-stained rock and the boardwalk are clearly visible on Google Earth). It would take about an hour from Somerset West.

Miller's Point and Boulders, Cape Town, South Africa

My slow start to the day had me running late and a trip down to The Cape of Good Hope would be all too brief to make it worth my while. Along the approach road, the M4, down the eastern side of the peninsular is a boat launching ramp called Miller’s Point, about 5kms south of Simon’s Town (Google Earth ref; 34 15’ 54”S 18 28’ 31”). Take the second entrance if coming from Simon’s Town.
Day-trippers are attracted by a sea pool that changes its water with the tide and offers salt water swimming without all that Great White Shark silliness. Gulls are attracted by the fishermen hauling their boats and catch from the sea. In turn, I was attracted by the gulls, but stayed for the Oystercatchers.

An attended car park is open until 18.00 after the sun had dropped behind the huge mass of rock to the west. Parking outside the secure car park is available at any time, but beware that trucks towing boats need a wide turning space.
Most obvious were the Cape Gulls. They are big, black-backed and abundant. Until recently, they were considered conspecific with the Kelp Gull. There were lots roosting in the car park, on the beach and on the ramp. Potentially it could be confused with Lesser Black-backed Gull, but the latter is an uncommon summer visitor only in the far northeast of the former’s range and has not been seen as far south as the cape. So there should be no cause for doubt, but are those yellow legs that I see behind the first bird?
Steps lead down onto a rocky coastline where an African Oystercatcher, Haematopus moquini, was calling hysterically at a couple who were walking nearby. It looked as if there was a pair which became increasingly upset and vocal as the couple walked in the sand above the high-tide mark. Perhaps there was a nest.
By coming from a different direction, the oystercatchers allowed me to get into a position to give a nice background to the picture. The bill and eye are very similar to the North American Black Oystercatcher, Haematopus bachmani, but the legs are pink instead of pale and this species is endemic to Southern Africa. 
A scan across False Bay brought rafts of Cape Gannet. A few were flying and occasionally stalling, and folding in their wings at the last second as they plunge dived (dove).
I began my homeward journey with a quick visit to the close by Boulders penguin colony (Google Earth ref; 34 11’ 52”S 18 27’ 12”E). The Jackass Penguins here are very easy to observe and will often shelter under cars, so be careful and check beneath your vehicle before you drive away. 
One individual was skipping back up the rocks to see his (?) other half. He had quite a jaunty step and was obviously looking forward to his assignation. Another couple had just been re-united at the top of the boulders and indulged in a touching, tender greeting before settling down for some preening and sunbathing in the last rays of the evening sun.
Passing Muizenberg, there was just enough light left to enjoy the waves coming ashore at the beach there. Hartlaub’s Gulls were waiting for scraps from the fishermen and I was able to see the faint grey collar and lavender rinse that often gets burnt out in strong light. 

Species seen; 10

Kirstenbosch Botanical Gardens, Cape Town, South Africa

Today, I had all day to kill in Cape Town. An early start should have seen me at Kirstenbosch Botanical Gardens on the morning slopes of Table Mountain for opening time, but the rest of the suburbs had risen before me and were in front of me on the motorway into the city. I have not experienced any significant traffic in South Africa before and I was dismayed to see the day start without me as the sun’s first rays hit the top of the mountain and gently slid down into the gardens as I watched from behind a gravel lorry on the N2. The 40 minute journey took nearly 3 hours.
The gardens are truly beautiful and my frustrations slipped quickly away once I had paid my entrance fee and began seeing some birds. Cape Francolin was ticked in the car park and a couple of Egyptian Geese sat atop the café near the turnstile of the top car park. Helmeted Guineafowl fussed with their chicks on the first of the many lawns and a young Verreaux’s Eagle soared with the massif behind it.
I wanted to move uphill to the protea and fynbos section of the gardens, but was drawn by bird calls and found a mixed flock feeding at the bottom of the slope. Cape White-eyes made up the majority with Cape Canary and Sombre Greenbul making most of the noise.
A tiny Muscicapa showed well in the sun and this time I paid more attention to the head. No streaks today, so this one must be a Dusky Flycatcher, though the underparts still look very pale to my tastes.
The protea and fynbos section of the garden is towards the top of the slope. Fynbos is the unique heath-like habitat that characterises the environment of much of the cape. It is very species rich with representatives from the grass or reed-like Restios, the heathy Ericas, the pincushion Leucospermums, and the magnificent Proteas. Such beautiful habitat and the high endemism make for a very rewarding birding experience.
Please take the bracketed section below with a pinch of salt. I am leaving it in just to cause confusion and divide opinion. It is probably a load of old toot, but it shows the dangers of over simplification. According to Gordon Lindsay Maclean, 'Roberts Birds of South Africa', the breeding season for Orange-breasted Sunbirds is from February until November, peaking between May and August. How very Northern Hemisphere! So the stuff about eclipse plumage (not discussed in Roberts), is almost certainly rubbish too.

(My first bird amongst the Ericas was an Orange-breasted Sunbird. The one above was still sporting his summer togs. Sunbirds along with male ducks go through a transitional stage known as eclipse plumage. I am still trying to determine whether the individual below is a juvenile or an adult male passing through his eclipse stage).
(It has the long central tail feathers, so I am plumping for an eclipsing adult but am prepared to take advise from anyone who can offer it.
Ducks lose all their flight feathers and their ability to fly during eclipse, not so the sunbirds from what I saw.)
(A Southern Double-collared Sunbird retained his flashy plumage and was still calling as though the summer was barely started rather than waning into the middle of March).
See above; the breeding season for Southern Double-collared Sunbirds is from April until November.
He was very faithful to a particular shrub and a female came out to join him in defending the bush. Their frequent sorties back and forth made me suspect that they may have a late brood deep in the fynbos.
On the highest tier the Cape Sugarbirds looked down from their lofty perches. Height is important for a sugarbird I am tempted to think. A small bush on a high slope seems to outrank a tall bush lower down, so the proteas at the top of the gardens are the most popular. This male was splendid with his long tail and had some red staining on his head from his habit of flower dipping.
A patch of Restios was very prolific with small flocks of Orange-breasted Sunbirds on the seedy stems. A Cape Robin-chat cowered in the low growth and this female Cape Sugarbird must have chosen the background especially for the bokeh.
Trying to take pictures of swifts is a pointless task unless of course it is a warm afternoon, and there is a patch of soft, freshly mown grass in light shadow to lie back on. A flock of about 40 Alpine Swifts were feeding above gardens and I lay back to enjoy them with a small piece of carrot cake. After watching for a while, I noticed that they would occasionally stop flapping in their pursuit of insects and cruise for a moment or two. Perhaps they had just caught something to eat and were swallowing it, but it gave a moment of predictability and a chance to get one in the camera sights. I still maintain that the effort taken outweighs the reward, but it is the only picture I have ever managed of an Alpine Swift (actually, there are two pictures in one).
An area of large trees along a stream is known as The Dell. It is in a deep depression at the centre of the gardens. I was still on my way down and stopped at a bench overlooking the well wooded Dell. I am not given to superstitions, but I do have one slightly weird practice; if ever I sit on a bench dedicated as a memorial to someone, I will acknowledge that person. The bench was in memory of a Rob James and I nodded to him as I sat down and asked if he had seen anything. At that very moment, my eye fell on a large shape in a tree.
Sitting out in the open, entirely exposed, was a Spotted Eagle Owl. “Ooh, look Rob.” I was conscious that I was having a conversation with a bench, but strangely, it didn’t seem inappropriate. I called the attention of another couple with binoculars who looked like birders and within a few moments, a crowd had gathered to see the owl.
A passing gardens guide told me that the owls (note plural, for the mate was further along the branch in a leafier spot) were often to be found in and around The Dell and that they had nested in the large tree just behind Rob’s bench. To my amazement, the owl allowed the crowd to come within about 3 meters to take pictures with their phones. Whilst I tutted to start with, the owl seemed so non-plussed that I couldn’t resist the opportunity.
A very classy restaurant near the main gate was filled with very classy customers in suits, and shiny shoes. I wanted to stop in for a drink, but a Malachite Sunbird caught my eye just outside. It was feeding from low flowers right by the restaurant’s veranda and I had to get down low on the path to get a good angle. I couldn’t help noticing the diners regarding me suspiciously as I sprawled across the fancy brickwork. Actually this happens quite a lot, but I felt uneasy joining them for lunch afterwards, so straightened my birding silks, brushed myself down and called it a day at the gardens.

Kirstenbosch Botanical Gardens are sited on the eastern slopes of Table Mountain, off the M63 Rhodes Drive (Google Earth ref; 33 59' 16"S 18 26' 08"E). The gates open every day from 08.00 until 19.00, but close one hour earlier during the austral winter from April to August.
If the gate is not yet open, early arrivals can explore the small area of forest on the right as they approach the upper car park.
The entrance fee is RSA 37 (@ RSA 11 =£1). Toilets, gift shop and cafe are all available.
Most of the birds below could have been seen in a couple of hours if I didn't keep stopping for pictures and carrot cake.
