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!

Stilts at LPPCHEAA

On the 1st of April, a few WBCP-ers (led by Mike L. and Arne J.) attended the groundbreaking for a wetland park at the LPPCHEA (Las Piñas-Parañaque Critical Habitat and Ecotourism Area). Finally!  Hopefully, this project, led by Sen. Cynthia Villar, will focus on the importance of the mudflats as a wetland (it is a declared RAMSAR site!) and as a green space in a city choked by urban developments lacking environmental planning.

Adri and I were there but unwittingly skipped the ceremonies as we were captivated by several Black-winged Stilts foraging along a relatively clean beach.  We had lost track of the time and got caught up documenting the graceful stilts as they were feeding along the waterline.

When we arrived at sunrise, I was delighted to see that much of the trash along the coastline had been cleared (still a lot left of course, I would think it almost impossible to clean all of it up, with more trash coming in daily with the tide).  The beautiful shell beach was exposed - revealing a diversity of gastropods and bivalves, together with a bit of plant litter: seeds, twigs (and sadly some plastic knick knacks).  It was definitely a bit of beauty one seldom would expect to find along the Manila beaches of the bay.



I could only imagine all the possibilities of having a clean beach in Metro Manila for the city-dwellers to enjoy.



A lone Common Sandpiper was busy preening in the golden monring light, stanind on a bit of muddy, discarded rubber/canvas/plastic.




A few stilts were on the beach at first, some resting and preening, others busy foraging for food. Many of them were quite vocal, twittering loudly.





There were few other migrants at the beach, although in the distance at the river mouth we could see several egrets, some herons and quite a number of waders.

A few Common Greenshanks flew past us, twittering loudly.




It was not only the birds out foraging, a man and his two young boys were also busy looking for shellfish in the shallow waters.




As the shadows receded with the rising sun, more and more stilts began flying in.  It was nice to see varying plumage, from the usual greyish markings of younger birds to elegant black and white plumage of the full adults.




Adri and I found a nice large log to sit on, under the shade of the mangroves.  The birds soon got used to our presence and began to get comfortable.

We practice in-flight shots with two Whiskered Terns.




And got a good laugh trying to outdo each other with stilts-in-flight shots.




Some of the stilts were flying back and forth right in front of us!  Sometimes they were too close!




We were not the only humans on the beach, several meters away was a man busy with his boat, being ignored by most of the birds.




A few greenshanks decided to join the stilts.




And one of the beach dogs also came out to inspect the debris that had been carried in by the tide.




Soon the tide began to turn and we could tell the ground breaking event had finished, because we could see large groups of people descending on the beach.  In the distance, a large group in orange jackets were busy cleaning up the coast.




Nearby, a group decided to take the DENR trash boat (it had a huge net to catch floating trash out at sea) for a quick spin.  The Black-winged Stilts paid no attention to the people (probably because the people were not paying any attention to them either!)




The tide was eating up the thin stretch of beach so we decided to start heading back.  We ran into some of the participants and volunteers who were with Rey Aguinaldo (DENR Region IV and LPPCEHA Project Manager).  We were happy to show them some of the stilts through the scope.  They expressed their surprise at the number of birds along the beach, even commenting that they were happy that the event (with its many people and loud sound system) did not flush or scare them away.




As we walked back to the car along the more shaded inland trail, we spotted other migrants: a noisy Brown Shrike and a confiding Arctic Warbler.






We also ran into several groups of Barred Rails and Common Moorhens foraging under the mangroves.

At the end of the beach near the car, we saw a small group of three enjoying a swim in the water.  It was not something I would recommend!  I am still hopeful though, that one day, Manila Bay will be clean enough for more recreational activities.  With the threat of reclamation looming, perhaps a wetland park is just what LPPCHEA needs. Not just for humans, but for all the other wild ones that need it too.




Keeping my fingers crossed.

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.


Whiskered Terns

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!
