Sea-watching and Lincoln Park, San Francisco, June 2012

Lincoln Park is situated on San Francisco’s ocean-side at the far west end of Geary St. A group of young men who had the shifty look of ne’er-do-wells the world over were loitering in the car park, but I was travelling light today, carrying only an old, cheap outfit while the good camera and lens are with the repairman. This would have been the perfect day to get mugged, I was even on my reserve set of binoculars. They could have had this old lot for the insurance.

Seal Rocks were immediately striking as I stepped from the bus. They looked a bit steep for seals and were covered with guano white-wash above the reach of the tide and the waves. Brandt’s Cormorants, and Brown Pelicans found a safe roost there. Closer inspection revealed a few Pigeon Guillemots and a single Black Oystercatcher.
Beyond the rocks, Common Murres flew by, just above the water’s surface. The prevailing direction was from right to left, giving the impression that their roosting site is to the north of the Golden Gate Bridge with their feeding grounds to the south.

Inland, a stand of pines refracted the early morning sun to beautiful effect. The areas close to the tops of the cliffs had been roped off to avoid erosion to the delicate plants on the slopes, but my potential insurance adjusters had stepped over them and were sniffing glue close to the edge.

The brisk wind coming in from the ocean reminded me that even in the second week of June, a pair of gloves would be no weight to carry. The Western Gulls and Common Ravens didn’t appear to notice the chill as they rode the wind rising up from the cliffs.

A path leads round the headland and a view back through the Golden Gate Bridge into the bay with Angel Island just beyond the iconic structure, would surely be a very picturesque sight on a clear day.

A California Sealion had caught a huge fish and was thrashing around in the water trying to subdue it and break it into bite-size portions. This attracted the gulls who were hoping for a few scraps. There were porpoise close to the bay entrance too. They hardly break the surface, unlike their more exuberant dolphin cousins. They just appear to roll gently at the surface, thier tiny dorsal fin barely visible at distance.

White-crowned Sparrows were very common along the path and a flock of Surf Scoters were seen close to the mouth of the bay.

Palo Alto Baylands on foot, San Francisco, June 2012.

I wanted to see if it was possible to visit the Palo Alto Baylands by public transport and found that it was, providing that you wear comfortable shoes and are prepared to walk the miles. Caltrain leaves from SanFrancisco station on 4th St. and takes an hour to reach California Avenue station (Google Earth ref; 37 25 45N 122 08 31W ). Walk east through the leafy suburbs along North California Ave, turn right onto Embarcadero and 45 minutes later you will be in sight of the Lucy Evans Nature Center (Google Earth ref; 37 27 35N 122 06 23W ). A dozen or so birds along the way included Chestnut-backed Chickadee, California Towhee, Western Scrub Jay, Western Bluebird and Brown-headed Cowbird.

I took the path from the duckpond around the northern slough to take advantage of the light. Black-necked Stilts and American Avocets were very obvious here and fed from the large expanses of mud at low tide. predicted a high tide at 10.30, but I was beginning to doubt this as the tide was so low at 07.30.

Out on the boardwalk, the water was still flowing out towards the bay. I caught a fleeting glimpse of a Clapper Rail in ‘Rail Alley’ as it darted up a side ditch. I wondered if my sudden appearance had startled it and hoped that if I sat quietly, it might come back out into the main ditch. After a while, it looked as if the rail had moved on, so I took a quick stroll to the far end of the boardwalk where a platform looks out over the bay. When I returned, it was to find tracks leading back out from the side ditch and unhurried Clapper Rail footprints on the raised island of mud in the middle of the ditch. It would have passed, in perfect light, within 8 feet, offering a fantasy photo opportunity to anyone with enough patience just to sit still for a few more minutes.

The thought haunted me for the rest of the day until I returned to the hotel and saw the results of my photographic efforts for this trip. I would probably have bollixed up the rail pictures and that would have been even more frustrating than missing it altogether. My camera and lens are in for repair this week and I can’t imagine how I ever coped without image stabilisation before.
Song Sparrows were very common in the salt marsh and their distinctive song proved to be the soundtrack for the day.

As well as the avocets and stilts, there were a few other waders such as Willet, Marbled Godwit and Long-billed Curlew, but all the peeps and the dowitchers were gone in this second week of June.
The tide did actually come in as predicted and quickly began to fill the channels inland, but strangely, one of the ditches was still draining towards the bay. Rays had come in on the tide and were feeding in the channel close to Bixby Park.
I had planned to cross the park towards Charleston Slough, but the way was blocked by the earth moving contractors, so I had to retrace my steps back out onto East Bayshore Drive.

The first bird that I saw on entering the approach path to Charleston Slough came as quite a shock. A red-wattled face with a blonde crest and a spangled body brought to mind a plate from my India and Southeast Asia fieldguide that illustrates Pheasants and Tragopans. Once home, consultation of said fieldguide gave me Khalij Pheasant, more commonly seen in the Himalayas. I was looking forward to entering this one onto ebird, but my initial shock at finding the bird was compounded when I found that it was listed on my software for California. That rather spoiled my fun with eBird, I do so look forward to hearing from them.

eBird has passed the details on to the local yahoo group which has caused some interest, so a few extra pictures have been posted here.

I swapped news of my Tragopan/Khalij Pheasant, with Irene, who in turn pointed out a juvenile Black-crowned Night Heron. It was being mobbed by Barn Swallows that did not want it near their young. Suddenly, it darted out its bill and plucked a young swallow from the air, killed it and gulped it down. I was nearly as shocked as the young swallow who was wondering where his sibling had gone.

A pair of American Avocets were behaving like first time parents in trying to protect their tiny chicks who were feeding out in the open. Every time that a gull flew over, one or both of the parents would take to the air and chase it away. Having sited their nest so close to a coastal gull roost, I wondered how long they would be able to keep it up.

Forster’s Terns, Snowy Egrets and a Surf Scoter were feeding on the leisure lake and the Black Skimmers seemed to prefer the island here to the one on which I usually see them in Charleston Slough.

I had walked as far as Shoreline at Mountain View in the hope of finding Burrowing Owls, but had had no luck in this respect. Instead I watched a Red-tailed Hawk gliding across the steep slope, then suddenly diving down to catch a Mallard from the shoreline. The catch was possibly too heavy for the hawk and it only flew a very short distance before landing. The duck was obviously very keen to escape and fought bravely, almost dragging the hawk into the water in the struggle, but finally she went quiet. The hawk seemed satisfied that the duck was dead and changed its grip in order to start feeding, but the duck had fooled it and with a last massive effort escaped back onto the water, leaving the hawk frustrated.

The duck received a round of applause from me for her cleverness, but we were both shocked a moment later when the red-tail rose into the air on the brisk breeze and dropped onto her ducklings which were cowering by the shore. The hawk grabbed one in each set of talons and flew off with the much softer option.

The route home took me along North Shoreline Boulevard towards Mountain View Caltrain Station. In a stroke of pure luck, I stopped beneath a palm tree to repack all my stuff before the hike back to the train line. I noticed pellets and a skull scattered around the base of the tree and looked up to find a Barn Owl looking down.

From California Avenue Caltrain Station to Lucy Evans Nature Centre  is a 3 mile walk. To return, the walk from Shoreline at Mountain View, to Mountain View Caltrain Station is about 2.25 miles. Wandering about generally, added up to a total of about 14 miles today.

Bukit Timah, Singapore, June 2012

Bukit Timah is a forested Hill in the centre of Singapore Island. I would venture to say that it may be the highest spot in the country, but don’t hold me to that. There is a steep initial climb for about 200 meters from the Visitor Centre before the gradient becomes more bearable towards the summit. All in all, the climb would probably not take more than 15 to 20 minutes, but that time might be better spent around the base of the hill where more birds seem to hang out.

At the entrance, a cycle track cuts into the forest on the right. Beware of mountain bikers here who assume that they have the right of way.

Pin-striped Tit-babblers were common along this track as were the Asian Glossy Starlings, Pink-necked Green Pigeons and Yellow-vented Bulbuls. Greater Racket-tailed Drongos were chasing relentlessly back and forth to feed a pair of chicks.

Please excuse this picture of a Banded Woodpecker which was taken from the deep, dark, wood and had to be enhanced dramatically to bring up the image. The bird was clinging to the trunk with its legs splayed wide to enable it to get closer to the trunk and listen for grubs moving inside. Its wings were spread to keep it from rolling from side to side on its keel.

The highlight of the visit was finding Hindhede Park. Even though the entrance is located right beside the Visitor Centre, I had never ventured into this section of the reserve. Primarily, it is a picnic and playground, but the forest is closing back in to reclaim the tables and climbing frames. More Greater Racket-tailed Drongos and Common Ioras were seen on the short stroll as far as the platform that looks out over the flooded quarry.

A photographer was trying to capture a shot of a Stork-billed Kingfisher diving for fish. He did this by throwing out a piece of bread which attracted the small fish. When the fish splashed, they in turn attracted the kingfisher which plunged into the shoal three times as I watched. This was the best that I managed, but there is more to come from my next visit, I can assure you.

Sadly, I have to put the Blue-eared Kingfisher down as a miss. We managed to scale the language barrier as the other photographer told me that he was waiting for the little blue kingfisher that comes later in the evening. He excitedly called and pointed at a ripple, then into a bank-side tree, but I just couldn’t see it. So I have two good reasons to return on my next trip to Singapore.

 Birds seen; 15

White-bellied Sea Eagle 1, Pink-necked Pigeon 10, Stork-billed Kingfisher 3, Banded Woodpecker 1, Common Iora 1, Black-naped Oriole 1, Greater Racket-tailed Drongo 6, Pied Fantail 1, Pacific Swallow 2, Yellow-vented Bulbul 8, Common Tailorbird 1, Pin-striped Tit-babbler 8, Asian Glossy Starling 12, Javan Myna 15, Orange-bellied Flowerpecker 1.

I made the journey to Bukit Timah as an extension of the trip to the Botanic Garden. Buses 67, 170 and 171 all pass by the Botanic Garden MRT station and continue to the stop close to Bukit Timah at Google Earth ref; 01 20 35N 103 46 31E. From here, look north to see the big aeriels at the top of the hill. Head towards them and cross the footbridge over the main road, pass under the little railway bridge on Hindhede Dr. and continue straight up for the Visitor Centre at Google Earth ref; 01 20 55N 103 46 37E.

Alternatively all three of the buses mentioned above pass within 200m of Newton MRT Station.

Botanic Gardens in Singapore, June 2012

No trip to Singapore would be complete without a visit to the wonderful Botanic Gardens there. I arrived by MRT at the Eco Pond end of the gardens, starting the day with the conundrum that is the swiftlets. 

I had spent a lot of time on them already, but this morning they were joined by a far easier species in the form of a Grey-rumped Treeswift. White-breasted Waterhens were common around the pond’s edge though they looked very nervous as they tended to their young. The Lesser Whistling Ducks were also keeping a watchful eye on their brood.

I was headed towards the Heliconia garden which overlooks Symphony Lake and attracts Sunbirds to feed from the showy flowers. An Olive-backed Sunbird male was first to show followed shortly after by the female.

A Crimson Sunbird came down to feed too, but dropped onto the far side of the flowers. On the other side of the lake, looking back towards the Heliconias, a White-breasted Kingfisher kept vigil.

I continued towards Swan Lake where there is a slope with some fruiting trees at the bottom. From the top of the slope, I was able to see the Pink-necked Green Pigeons which were feeding, then took to roosting as the day warmed up and the fruit began to ferment.

The usual angle of approach for the Green Pigeon is from below as it commonly feeds in the tops of fruiting trees, so it was nice to get a picture that does not prominently feature the vent.

I returned towards the MRT station passing the proud parents of three White-breasted Waterhen chicks that crossed the path in front of me and stopped for a quick photocall.

Of course Singapore Botanic Garden is famed for its variety of dragonflies. I hadn't intended to do any oding today, but when a bright red jobbie lands on a Heliconia, it is hard to resist.

Venus Transit and Paser Ris, Singapore, June 2012

And so back to Singapore as this itinerary turns for home. A transit of Venus across the face of the Sun left me the opportunity and excuse for a lie-in before being helplessly drawn to Paser Ris.

The approach to the mangroves along Sungei (River) Tampines is always productive with a Sunda Woodpecker, Black-naped Orioles and a Collared Kingfisher.

The park itself is home to sunbirds such as this female Brown-necked Sunbird.

I discovered Paser Ris by accident on my first ever birding outing here and cannot pass through Singapore without making a visit. It was a quiet day today without the excitement of previous visits, but very pleasant just the same.
The quietness of the late afternoon visit allowed me the time to try to get a picture of a swiftlet. The only advice I have ever given about photographing swifts was ‘don’t waste your time’, but I have never been one to heed my own advice.

The swiftlets here are very difficult to identify, well, they keep flying about! I wanted to try for a picture to see if that would be able to tell me what I was unable to see with my naked eyes.

I had managed to separate Germa(i)n’s Swiftlet earlier in the trip by virtue of its lighter rump, but these showed a much fainter marking if at all. The obvious tail notch and plain underparts keep leading me back to Himalayan Swiftlet, but I cannot commit myself on the basis of these pictures.

On Sungei Tampines, the Grey Heron roost was busy. I would love to think that this individual shouted “Boo!” as it landed.

There are plenty of fruit trees around the park and a couple of them, down by the shore were attracting Pink-necked Green Pigeons and Asian Glossy Starlings to feed.

Birds seen; 21

Grey Heron 8, Striated Heron 2, Brahminy Kite 1, White-bellied Sea Eagle 1, Little Tern 2, Spotted Dove 2, Zebra Dove 2, Collared Kingfisher 4, Blue-throated Bee-eater 4, Brown-capped Woodpecker 1, Common Iora 3, Black-naped Oriole 2, House Crow 6, Pacific Swallow 4, Yellow-vented Bulbul 12, Ashy Tailorbird 4, Asian Glossy Starling 60, Javan Myna 40, Brown-throated Sunbird 2, Olive-backed Sunbird 1.

Powerful Owls in Sydney Botanical Gardens, June 2012

Sydney’s Royal Botanical Gardens were bathed in sunshine for a very quick surgical strike in search of a pair of Powerful Owls. They proved to be very easy to find given that I had completely failed on two previous attempts.

Look for bat wings and possum tails scattered on the ground among the plentiful pellets, then just look up. Start your search in the ficus tree as the driveway splits, just before the Governor’s Mansion. Below is the male. The female preferred another ficus tree just across the driveway.

Mission accomplished, I moved on and took the long way back via the ponds where a Black Cormorant was roosting in the trees on one of the small islands. A black plastic sack stuck in one of the branches may have been another attempt by the gardens to save its trees.

In the past Australian Ibis and at least two species of cormorant nested on the little islands in the pond The ibis appear to have reduced significantly in number over the last few years and I have seen very little nesting behaviour on my recent visits.

I continued across the lawns towards the gap in the wall into the herb garden. Just here, another of Australia’s night birds, the Tawny Frogmouth was seen in a very open position.

Birds seen; 11
Maned Duck 4, Chestnut Teal 3, Little Black Cormorant 5, Australian Ibis 15, Dusky Moorhen 8, Masked Lapwing 4, Silver Gull 6, Powerful Owl 2, Tawny Frogmouth 1, Noisy Miner 5, Welcome Swallow 3.

Bi-Centennial Park, Sydney, June 2012

Sydney was sporting an autumnal look as the southern winter approaches. It was cool enough to have the locals reaching for their jackets, but 12C is a perfect temperature for an overweight sweaty bloke who was planning a bit of a hike. 

I started from Concorde West as usual, but was planning to cover more ground today and return by ferry from the wharf on the Parramatta River. As usual, birds were seen before even leaving the station with Pied Currawong, Noisy Miner, Australian Raven and Rainbow Lorikeet seen before passing under the road bridge at the end of Victoria Ave. A flock of 30 Sulphur-crested Cockatoos flew raucously over and alighted on the large aerial just inside the park.

Yellow Thornbills, Spotted Pardalotes, Grey Fantails, and Superb Fairywrens formed a mixed flock to welcome me into the scrub along the path that passes the freshwater ponds. 

A Purple Gallinule reflected in the pond that it shared with a few Chestnut Teal and a Pacific Black Duck.

The water level in the lagoon was as high as I have seen it before. There was not a wide variety of birds to be seen this morning, though Chestnut Teal, Grey Teal and Black-winged Stilt were plentiful. A few Black Swans drifted carelessly across the surface with one taking time to show off the flight feathers that so often get missed on the closed wing.

At the far end of the lagoon, I stopped in at the hide for a while. The high water had covered the mud which is usually enjoyed by the tiny Red-kneed Dotterels and it had concentrated the Black-winged Stilts around the small island that they shared this morning with the Australian Pelicans.
On Homebush Bay behind, a few scuttled boats provided roosting spots for the missing Dotterels as well as Anhinga, Silver Gulls and Pied Cormorants.

Beyond here, I was venturing into new territory. I had arrived in Sydney early this morning and the rest of the day was mine, so I had no time restrictions and was able to continue across the Bennelong Parkway bridge at Google Earth ref; 33 50 05S 151 04 33E. A Rufous Night Heron roosted in the mangroves overlooking the side channel here and a Striated Heron watched patiently from the barrage. 
I took the path through the Olympic archery ranges before cutting across Hill Road into the Narawang Wetlands which had been my main purpose for this morning’s visit. The marshes here are man-made, managed for Bell Frogs with a boardwalk passing through much of the system. There are shallow and deep pools with lots of reeds, rushes and water vegetation, but not much by way of birds. 

A few Superb Fairywrens were seen among the rushes and some Australian Grebes dived and disappeared into the reeds at my approach, but most of the action came from the higher trees around the edges. Black-faced Cuckoo-shrikes were seen perched in the topmost branches and a Grey Butcherbird sat out proud on a snag.
My secondary target for the day was a visit to Birdlife Australia Discovery Centre. The gates from the wetlands leading into Newington Armory were closed, so I had to take the long way round via the gaol. The public displays were closed when I arrived, but the friendly and helpful staff opened it up for me to have a quick look. After a quick glance at my waistline, they warned me that the gap in the fence was quite narrow and then pointed me towards the exit of the armory. Sure enough, for a chap with a pie dependency, it was a bit of a squeeze to get out. By the river here there is another wetland with viewing gaps cut into a screen through which good numbers of Chestnut and Grey Teal could be seen, but more locked gates that looked as if they did not open very often for casual viewing, blocked further penetration into the area.

There is a pair of White-bellied Sea Eagles that feature as stars of the Discovery Centre’s webcam, building a nest nearby each year and raising their chicks under thousands of watchful eyes. The bird perched in the mangroves across the Parramatta River was possibly one of the pair which should be returning to their duties later this year. It was time to rest my weary legs and I took the time to try to get a long-distance shot of the eagle.

A Brown Hawk flew past and flushed a White-faced Heron that had been picking it way along the shore towards me.
The ferry timetables did not suit me at this time of day, so I ended up on the bus which runs between the wharf at Google Earth ref; and Strathfield Railway Station (a couple of stops closer to the city on the same line as Concorde West).
