Mekeni, mamilang tamung ayup!

("Come, let's count birds!" in Pampangueño)

Migratory birds are currently on the move for Autumn migration, and I look back to last February where we joined the indefatigable Arne J to check out the environs of Manila Bay to survey the waterbird population. Our group was composed of myself, Adri, Tinggay, Angelo and Arne. We were ready to count birds!

Manila Bay is a significant feeding and staging area for migratory waterbirds, and needless to say, the changes around its shores in the name of development and progress may be to the detriment of our feathered world travelling friends. It is important that regular surveys are performed, especially during peak migration to keep records which may be useful for future decisions. Arne has extensive experience with the Manila Bay area and has worked with Wetlands International, providing valuable data. Of course we were thrilled at the chance to join him on a survey!

Our initial plan was to explore a few mudflats along the coastlines accessible by boat at the northern part of Manila Bay where the Pampanga River meets the sea. A few Kentish Plovers were scuttling on the beach, while Whiskered Terns flew above us. There were also large numbers of black-headed gulls were flying overhead towards the sea, so we were excited to get going. We also got a single Caspian Tern flying overhead! It was a lifer for me! 

Because of the low tide, we had a difficult time getting to the bangka, having to balance and strategically step through the thick mud. We finally got to the bangka, but then, we couldn't move! We were stuck in the mud! The water was too low and we were grounded! Our bangka got stuck in the mud and we weren't getting anywhere. It looked as if our initial plans could not push through.  So we got out again and walked back through the mud back to the beach. After washing off the mud from our legs, it was decided that we just explore the banks of the Pampanga River.

We started off walking along the road on the west bank of the Pampanga river. 

Wow!  There were a lot of Black-headed Gulls. A LOT! They looked like little white islands from the distance, sparkling in the hot sun.  But a look through the scope revealed them to be flocks of gulls and terns! Most of them were preening, but some seemed to be resting or asleep.


There a several waders as well: egrets, sandpipers, stints, plovers, greenshanks - mixed in with the large flocks. We also spotted several more Caspian Terns mixed in with the flock, their larger size orange bills making them easy to spot.


We spent the entire morning counting on the west bank of the river, breaking for lunch at midday.  Tinggay provided us with a wonderful meal, which we enjoyed by the roadside under the shade of a tree.

We got back on the highway and crossed a bridge over the river and then proceeded to find our way to the opposite side of the river.

This time, in the afternoon, it was mostly resting Whiskered Terns which we counted!



The heat was stifling under that hot sun, and the east river bank provided even less shade than the sparsely tree- and bamboo-lined west bank.  We took refuge in the shade of the tall grass when we could.




There were also several Black-winged Stilts feeding in the shallow waters, accompanied by a few Common Greenshanks.  Always elegant, whether standing on the impossibly long pink legs, or flying above the water, Black-winged Stilts are among my favorite waders.





Every now and then Adri would spot a large flock of incoming waders: sometimes terms, sometimes plovers or sandpipers.  They were flying so high up in the air!




Most of the east bank nearest to the sea was occupied with large fishponds.


Their fences provided perches for many of the terns.  This guard dog didn't mind the birds but it sure made quite a racket barking at us walking on the dirt path several meters away!



Arne and Angelo made it all the way to the shores of Manila Bay, I think!  We ran into them already walking back and so we made a u-turn as well.



It was getting late in the afternoon and the shadows getting longer.  The earth was cooling down a bit and the scenery was very tranquil.



We thought we were already done with our counts, but wait! There was more!  We spotted a few more waders at the beginning of the asphalted road on our way back.  There was even a Peregrine Falcon patrolling the fields at sunset, perched on a low dike!



In the end we came up with a count of more than 30,000 waders and wetland-associated birds!  Spending an entire day counting on the survey was exhausting and so I appreciated Arne's enthusiasm and professionalism even more after the experience.  At the end of the day as we drove off with the sun setting behind us we were in the good company of passionate birders, the total numbers were amazing and it was all well worth the back breaking and eye-crossing job of counting waders for almost 12 hours.


In the morning after our retreat from the original plan!

Manila idylls: Terns and Gulls of the Pasig River

Old Manila conjures up images of the walled city of Intramuros - adobe fortifications and cobblestone walks, churches and ruins, bridges over the river Pasig and plazas.  But wildlife?  Not really on the radar when one thinks of the historical district!

Last February 26, the Battle of Manila in 1945 was commemorated with an open-to-all festival in the park at Buluarte San Diego organized by Carlos Celdran.  Before the party kicked off, the WBCP decided to introduce another side of the city to its residents: birds of course!

Late in the afternoon, we met a small group of mostly first time birders at the Plaza Mexico


No traffic on Sundays!  Facing the Aduana building ruins.

Participants included repeat guided walk participants, urban sketchers, families and barkadas looking to try out birdwatching and curious about the birds of Manila.


Mike and some of our participants.

No worries about spotting birds: the Pasig River was alive with Whiskered Terns and even a few Black-headed Gulls!



Terns perched on the wires crossing the river (Can you spot the gull?)

We spent a lot of time admiring the graceful birds as they skimmed over the dark waters of the Pasig.

Black-headed Gull

While many coastal cities all over the world are plagued by aggressive gulls, the birds here were still wary of people. WBCP-er and Manila-resident Rache G. says that they used to be persecuted by those who lived along the banks, who made them targets for their slingshots and airguns.  Thankfully, the recent initiatives to clean up the river side has diminished these threats, and now more of these coastal birds are commonly sighted along the river banks inland.

The Whiskered Terns perched on electric and communications wires were dwarfed by the much larger gulls, and it was amusing to see them give way so their larger neighbor could have some perching space.



In (almost) perfect alignment!


One of the Black-headed Gulls was already approaching full breeding plumage and it actually had a black head!  It was an excellent example to explain winter plumage and migration to the bird walk participants.



Black-headed Gull approaching full breeding plumage:
so that's why it's called Black-headed!

Besides the gulls and terns, we were able to spot several other birds.  Pacific Swallows, and Glossy Swiftlets glided smoothly over the waters also.

Along the banks were several Little Egrets perched on floating clumps of water hyacinth.  On the few trees and electrical posts we spotted Zebra Doves, Asian Glossy Starlings and Yellow-vented Bulbuls.  

At the Maestranza ruins, Eurasian Tree Sparrows were enjoying dust baths. A lone Brown Shrike was hunting amongst some bougainvillea bushes.  We were surprised when one of the participants pointed out a Java Sparrow in one of the trees!

As sunset approached, we were treated to playful pair of Philippine Pied Fantails and to cap off the birdwalk, a beautiful Common Kingfisher was spotted!

Urban landscapes are more than just buildings and people, more than historic monuments and modern structures.  Cities are home to wildlife as well!  All we have to do is open our eyes to see our wild urban neighbors whom we share the city with.

Cheers to urban biodiversity!

the mystery gull and the wild gull chase


it all began when adri and i found ourselves back in the balanga city wetland and nature park, one week after the awc.  this time we were with american birder e.m., who was interested in seeing waders in their winter plumage. surprisingly  there weren't as many birds as the previous week, but we still had good views of the usual egrets, herons, greenshanks, redshanks, plovers, sandpipers, stints, stilts, terns and gulls.  it being a sunday, the park full of people enjoying the ocean breeze and wading in the cool waters (which were unfortunately part of the very polluted manila bay).  em was especially delighted to see several locals toting binoculars and cameras, with obvious appreciation for the birds. it was a very relaxing morning, and as we were leaving, we decided to scan the exposed mudflats where various waders, gulls and terns were quickly gathering as the tide continued to rise.

and there it was. a gull which was obviously larger than the hundreds of black-headed gulls. even in the white heat of mid-morning, its grey brown plumage stood out in the sea of the mostly white black-headed gulls.

and adri and i had no idea what it was. we could also make out a black tipped orange-ish bill, and it behaved quite differently. it ran around on the mudflat at the waters edge constantly, very active compared to the black-headed gulls which mostly stood in one place while preening and would fly off after.

might it be a herring gull, em asked.  it could, we answered. the kennedy field guide had 3 suggestions: herring gull, slaty-backed gull or black-tailed gull.

at a loss, we took down notes and tried to document the bird.  it was too far away for both my short 350mm lens and even for adri's digiscoping set-up.  the harsh lighting and strong wind did not help our cause.


the mystery gull: with pictures like these it could be the loch ness monster

that night, adri posted a "possible herring gull" message on the wbcp facebook page, but nothing could be confirmed. black-tailed gull though was looking to be a better candidate, according to more experienced birders.

we didn't think it would generate much interest, but little did we know that 2 wbcp-ers, irene and rob would be back in balanga the next day to try to find the mystery gull.

did they find it? no, but they did find and photograph a beautiful laughing gull, the first record in the country!

now, that picture got several people twitching, and the very next day, i found myself in the company of a group of them: ivan, mel, rob, irene, tonji and sylvia! what the hey, it was still just past january (my personal "waterbird season") so might as well try to pin down the id of sunday's gull, and maybe get a laughing gull lifer! besides, it was a school holiday. adri, unfortunately could not join us as he was off guiding another group.

we all arrived at the wetland park just before the peak of high tide, which again would hopefully gather the birds closer to shore. it was now a weekday, it was virtually empty of people, although the stifling heat and burning sun could have also chased any normal person away.

we scanned the nearby mudflats again looking for any unusual gull. nothing but whiskered terns and black-headed gulls. it was a hard wait under the hot sun. later, a few common terns caught our interest, but still nothing more interesting. we waited in anticipation as the gulls and terns began flying in as the ocean level rose. a couple of great crested terns (i was excited about them the last week though), still not very interesting.

if only they could always be side by side for size comparison

when it became painfully obvious that neither mystery gull nor laughing gull was there, we decided to move to another baranggay where we could take a bangka out to look around the fishpens.  talk about a determined group!  somebody likened it to looking for a needle in a haystack.

whiskered terns and black-headed gulls


so we took two small outrigger boats out, and circled the nearby fish cages and even took the boat all the way back to the wetland park. for the next couple of hours: black-headed gull and whiskered tern galore.

whiskered terns all in a line

a sand martin, spotted by rob, flying with some swallows over newly planted mangroves was consolation enough.

on the way back we did get out of the bangkas one more time to take a look at some fishponds. more waders, but no gulls. and no unusual waders.

oh well, you win some you lose some. we left balanga as the sun was setting. mystery still unsolved.
