Checking out Candaba

Last week, Adri and I went on a quick trip to check out the road conditions at Candaba and found ourselves walking under the hot morning sun!

Upon arriving, we stayed on the highway straight towards Brgy Paligui to check out the back way, which turned out to be under water!  The farmers were already preparing some of the fields and large flocks of Wood Sandpipers were moving around.  Egrets and Black-winged Stilts were also a-plenty. We were hoping to get a glimpse of a pair of recently sighted Glossy Ibis but no luck.

With the back way unavailable even by foot, we back tracked to Brgy Bahay Pare and tried our luck there.  The dirt road was looking good: rough but dry, and some farmers were out working.  Upon reaching a familiar bend (where there was a domesticated duck pen right before the irrigation pond), we were faced with an evil looking mud puddle.  Deciding not to risk getting stuck, we asked permission to park by the road.

"Good idea," the farmer said, "you're sure to get stuck before you reach the ponds!"

As we geared up to go, the sun was already shining bright.  A cool and pleasant wind blew though, signs of the changing seasons.

Pairs of Pied Bushchats greeted us along the path.


Olive-backed Sunbirds (not really something you would associate with Candaba) sang cheerfully from the thorny camachile trees.


We flushed Lesser Coucals along the way, they took curious looks at us before disappearing into the tall grass.



As we came up to the ponds, we were surprised to see that they were choked and overgrown with grass and greenery and that hardly any water could be seen!  Perhaps this season's rains have not been enough to flood the ponds which were surely drained last summer for planting and irrigation.

Larger birds were easy to sight: Grey Herons and Purple Herons and Black Crowned Night-herons stood in silent patrol.  Small but frequent flocks of Wandering Whistling Ducks and Philippine Ducks flew by, but were quickly swallowed up by the greenery as they landed on the covered waters.



We made our way west of the ponds in the direction of the highway.  Most of the fields were still under water.  Whiskered Terns, all sorts of egrets (Little, Intermediate, Great and Cattle) and Herons were perched on small islands of land. 



Strangely, we saw a few Garganey which had landed right beside a large congregation of domesticated ducks!  They seemed diminutive swimming beside their hybrid cousins!



I think it's the first time I've seen migrant ducks swimming with domesticated ducks.

In the distance, a few Philippine Ducks were swimming in the open, flooded waters.  A lone Tufted Duck seemed a little lost by itself.

Nearer to us, many Little Grebes were popping in and out of the water in the floating vegetation. They were quite vocal and I realised that I had never really paid attention to what they sounded like before.

We passed by a duck farmer who had collected some duck eggs and was leaving one of his dogs to watch over the ducks.  He mentioned how high up the dikes the water was during the previous 2 typhoons Karen and Lawin but how the weather was improving.  He was wondering from which direction we had come from as we were now nearer the back way which was flooded and inaccessible.  We pointed in the direction we had come from and he gave a little scratch of his head. (I could almost hear his thought bubble: Crazy birders!).  "Not many wild ducks yet," he said out loud, "Just the ones that are here all year round. Four more days of this sunny weather and the road will be dry and passable."

It was already nearing noon and so we made our way back to our car.  All the usual suspects were out: flocks and flocks of Red Turtle Doves and Zebra Doves, noisy grassbirds and warblers, Yellow and Cinnamon Bitterns flying low across the ponds, Shrikes defending territories, Gerygones hopping about the rain tree canopy, swallows and bee-eaters gliding gracefully above  the fields, rails nervously crossing the paths.

As we left the pond area, a stately Purple Heron flew near us.


We had a very nice surprise on our walk back.  Several Eurema butterflies were puddling on the road!  They flew up in the air and surrounded us like yellow confetti as we passed them.


They quickly settled down and allowed us to get low shots of them delicately sipping minerals from the still damp ground.  I never thought this would be a sight I would see in Candaba!


Uneventful but all in all, it was a very pleasant walk and morning - hopefully a good sign of good birding days at Candaba ahead.

Twitching the Candaba teals

As I mentioned in my previous post on Candaba, a couple of days after Adri and I did our ocular, Rob and Irene and Mel spotted a new country record: a Baikal Teal.  After a few days, a duck which was spotted earlier by Kevin Artiaga (one of Lala's students), was identified as a Falcated Duck (also known as Falcated Teal), another country record!

Exciting times again for Candaba, after last year's Baer's Pochard.

With Adri out on tour, I was happy to tag along with Tere, Alex and Drew to twitch the country rarity.  Meeting us there were Tina and Neon ready with their bazooka lenses. Mads and Jude were also following.  A daily stream of visitors kept us up to date on the sightings, it was obviously a big deal to the local birding community to have two new country records at a very accessible location.

When we arrived, the plains and ponds were just being lit up by the golden morning light.  In front of us was the remaining pond, filled with thousands of ducks: mostly the endemic Philippine Ducks, some resident Wandering Whistling Ducks, and the migrants of course: Garganey, Northern Shovellers, Northern Pintails, Eurasian Wigeons, Green-winged Teal, Tufted Ducks.  The challenge was on to find a single Baikal Teal and a single Falcated Duck.


This pond is where we had to find the ducks.

As we surveyed the ponds, every now and then a flock of Black-winged Stilts would take to the air, elegant and graceful as ever.


Black-winged stilts in flight.


The skittish Philippine Ducks would also suddenly lift off noisily from the water's surface, joined by a few migrants.  They would circle the ponds and land again, with just as much splash as they made taking off.


A frenzy of Philippine ducks.


A Eurasian Coot swam quietly near us.


This coot was quite close.


We were all quietly concentrating on looking at each and every duck (something we really should do, even without specific target in mind: that's how unusual sightings are made!).

And then, in a sea of fl0ating kangkong leaves and blossoms, a brilliant emerald green suddenly popped out.  It was the Baikal Teal!


Can you spot the Baikal Teal in this photo? (See the close-up below)


A beautifully plumaged duck: the Baikal Teal in the floating vegetation.


It was quite a distance away, thankfully it was in the vicinity of a small bahay kubo in the middle of the pond, which made it easier to point out to the others.


The teal was somewhere here.


Yay!

It was busy preening itself, so every now and then its head would disappear into the kangkong.  Later it would even go to sleep, its head tucked under its wings.


It became even harder to spot when it tucked its head in to sleep.


It's a good thing it had a very distinct head pattern and color, which made it easier to spot once you knew its general location.


Here it is!



Later it would move around, never flying up but paddling across the pond or flying low short distances. As long as we kept our eye on it from time to time, it was easy to keep track of it or even to find it again.


It moved about in the kangkong, mostly half hidden with only its head sticking out (thanks to Drew for the enhanced i-phone-scoped photo on the corner!)


High fives and thumbs up all around!


Birders and photographers enjoying the Teal, even if it was quite a distance away.


As we were observing the Teal, suddenly an Eastern Marsh Harrier showed up, spooking most of the ducks into the air (but thankfully not the teal).

While we were watching the aerial display, Mads suddenly exclaimed: "Nakita ko na sya!" ("I've spotted it!") referring to the Falcated Duck.

Scopes, cameras and bins suddenly zoomed in on to the general location Mads was pointing to, which was even further than the location of the Teal!


The Falcated Duck is somewhere here, with some Philippine Ducks and Northern Pintail.


Sure enough, swimming with several Philippine Ducks was the target. It was a handsome duck, with a deep chocolate, head which glossed a bright green under the sun. It had a white throat and spot at the base of its beak.


The Falcated Duck was busy preening, it's green glossy head shimmering in the sunlight.


Like the Teal, it was busy preening itself, and every know and then we could see the curved feathers on its side and back after which it was named.

Yay again!


A short video of the Falcated Duck, thanks to Tere for sharing this i-phone scoped video! (Remember to watch it in HD)

It's great to have had the chance to observe these new country records.  We couldn't use our normal Kennedy field guide as it didn't have these species' descriptions, so we had to refer to other field guides.


No Kennedy guides were used that morning!

These sightings once again highlighted the need to preserve the remaining wetlands of Candaba which have all but been converted to great swathes of rice fields to feed the burgeoning population. The earth that feeds and shelters us needs to feed and shelter those we share it with too.

Candaba to start the birding year

Candaba is always a good idea to start the birding year.  A few days into 2016, Adri and I wanted to check out the roads leading to the ponds. A late December storm had flooded most of low lying Bulacan and Pampanga and Adri wanted to check out accessibility for his upcoming trips.

We started out at the back route at Brgy Paligue where the dirt road leading down from the highway was obviously not passable to most vehicles.  The first 10 meters or so was sticky mud, deeply rutted by tractor tire and still soft.  After that the road was quite dry and hard - but it hardly mattered since the first part was not passable.  We decided to walk to the mayor's ponds - many of the farmers were out working: plowing and tilling the fields to ready them for planting.

It's the time to ready the fields for planting.

Hundreds of Whiskered Terns were flying and landing all over the muddy fields, while a few egrets (all present: Cattle, Little, Intermediate and Great) congregated on some plots.  Every now and then a cloud of Black-winged Stilts would take to the air in their mesmerizing synchronous flight.

Whiskered Terns perched on the mud.


Egrets, egrets, egrets.


Along the path, Striated Grassbirds, Clamorous Reed Warblers, Zitting Cisticolas, Pied Bushchats and Common Kingfishers flew back and forth.

A male Pied Bushchat always has a female somewher nearby!

In ditches filled with water hyacinth, Yellow Bitterns, Common Moorhens, White-browed Crakes and White-breasted waterhens played hide-and-seek.  When we arrived at the back ponds, a Lesser Coucal was enjoying the hot morning sun.

A Lesser Coucal sort of out in the open.

As we approached the mayor's ponds we flushed the Red Turtledoves who predictably flew to the tall eucalyptus trees across from us.  We were happy to see several Philippine Ducks swimming in the vegetation choked water, with a few Wandering Whistling Ducks hiding nearby.

Philippine Ducks!

As we moved on, we also saw a few Green-winged Teal. A Black Bittern flew by and landed in the open quite a distance away.

In the distance somebody fired a few gun shots and all of a sudden the air was filled with hundreds of ducks!

Ducks in the air!


By then it was getting VERY hot and so we decided to walk back to our car on the highway and try out the roads from Brgy Bahay Pare and check out the ponds from the other side.

I saw all the farmers with their plows and carabaos working hard under the hot sun and reminded myself again to always finish the rice on my plate. (Not only did the farmers work hard for that rice, but the birds lost their habitat for it!)

Farmers busy in the fields


We had no difficulty at all on the dirt roads to the ponds.  On the un-planted plots of land nearing the ponds were several Wood Sandpipers foraging in the mud.

One of several Wood-sandpipers.


At the ponds we were pleasantly surprised to see many other migratory ducks.  Aside from the Green-winged Teal we had spotted earlier, there were also Northern Shovellers, Eurasian Wigeon, Tufted Duck, Garganey, and a lone NorthernPintail.  We thought we had spotted a Gadwall but we lost it on the scope and couldn't find it again for confirmation.

A Eurasian Wigeon and a Philippine Duck.


An Eastern Marsh Harrier flying over the ponds momentarily distracted us. Adult and juvenile Moorhens walked on the kangkong and Little Grebes would pop in and out of the water.

By this time the sun was bearing down heavily on us and waves of shimmering heat were making it difficult for us to view the ducks. The very still Grey and Purple Herons and Black-crowned Night Herons began to look like shiny mirages in the green.  


So, happy with the morning's sightings and having confirmed that the roads were passable, we decided that it was time to go.  Not too bad starting the birding year with several hundred ducks and waterbirds!


Sidenote: a few days later, Rob H., Irene D., and Mel T. would spot 2 ducks which were country records!  Looks like we need a return trip to Candaba soon!

a lesson in conservation at Candaba

Bringing another small group (separate from those who went to Bohol) of my Conservation Biology students to take a look at a classic example of wetlands conversion at Candaba allowed me an opportunity to twitch one of the rarest ducks in the world: the critically endangered Baer's Pochard.

The classification of critically endangered is not a very good category to be in, it means that this species is considered to be facing an extremely high risk of extinction in the wild. And with an estimated 150 - 700 mature individuals left in the wild, the Baer's Pochard sadly and definitely belongs in this category.

The key reasons for its rapid decline? Hunting and wetland destruction in both its breeding and wintering grounds.

When we arrived at the ponds, I quickly allowed a couple of hours for birding.  We were lucky to have a display of power by a pair of Eastern Marsh Harriers, who spooked the ducks into flying up into the air, to the delight of the group.

More than half of the main pond (the only remaining pond) had already been drained and converted to rice fields for the season, and so the ducks and other water birds were all crowded into a bit of water left on the side of the house and rundown DENR station.  It was ironic that, as the ponds were now being converted to rice fields, for the first time in several years we could see several species of ducks together in the pond.  I remember in the first couple of years that I started birding, the whole of the pond looked like that!  

There were the resident Philippine Ducks and Wandering Whistling Ducks. Joining them were the migrant Northern Pintails, Green-winged Teal, Garganey, Northern Shovellers, Tufted Duck and Eurasian Wigeon.  Then there were the not so common migrants: Gadwall, Common Pochard and of course the star: a lone Baer's Pochard.

Also included were several Purple Swamphens, Purple and Grey Herons, white egrets (Great, Intermediate and Little), White-breasted Waterhens, Common Moorhens, White-browed Crakes, Pheasant-tailed Jacanas, Little Grebes and even a Eurasian Coot!

I expected to run into a few birders and photographers on our trip, and sure enough we did.  While my students were doing their interviews of the locals and the recreational visitors (mostly bikers), Adri called me to tell me that they had spotted the Baer's Pochard.  I quickly walked over to where the birders and bird photographers were standing.

And there it was.  Well-hidden behind the floating kangkong was a dark head and a chestnut brown breast.  It was barely visible!  I was amazed they had even found it as it was quite far away towards the middle of the ponds.  What gave it away of course was the more distinctive Common Pochard beside it,  all previous reports the past week had these 2 ducks sighted together.

On the right is the bright chestnut head and white back of a Common Pochard.
Hope as we did for it to come out for a better view, it remained concealed. No one wanted to take their eyes of it, in case it suddenly decided to expose itself.

Every now and then another duck would pass in front of it or behind it. We were hoping the jostling it got from a couple of Northern Shovellers and a Garganey would wake it up and force it to move out in the open, but we had no such luck.


We were hoping that the other ducks, like this pair of Northern Shovellers, 
bumping into the resting Baer's Pochard would jostle it into the open. No such luck though.

Once in a while a white eye would peek from behind the vegetation, causing a bit of excitement in the group.  But that was as good as it got that morning.

Soon I had to go back to my students to process their interviews and their short morning experience. Later, we ran into Alex, Tere, Felix and Brian.  I urged my students to converse with the birders.  Alex gave a wonderful summary of the state of the Candaba wetlands which I am sure they enjoyed and appreciated.


Alex with my students

I am still not quite at ease having been assigned to co-teach the subject of Conservation Biology, having had no formal education or training of it.  Of course, my part had to do with genetics, which I was comfortable with.  But I am glad that I had the chance to share with my students whatever I had been learning vicariously about conservation from my passion for birding and my birding experiences.

Again, again

And so we were back in Candaba just as the sun was rising.  Despite having a lunch appointment, we joined Melanie for a very quick trip to the wetlands to check out the migrants.  This time we had a scope with us!

And it was a good thing we did!  The ducks were off to the opposite end of the pond, half hidden in a variety of semi-aquatic vegetation: grass, kangkong, water lilies, water hyacinth and lotus!

There were many Philippine Ducks and Wandering Whistling Ducks but we spotted several species of migratns as well.  There were Garganey, Common Pintails and Northern Shovellers.  Careful observation through the scope revealed a few Common Teal and even Eurasian Widgeons!  Rob and Irene also pointed out a female Gadwall in the mix. Too bad they were too far away for any decent photos!

Of course there were the common Black-crowned Night-heron, Purple Heron, Grey Heron and an assortment of white egrets.  The Purple Swamphen were still very visible, foraging in the vegetation.

Later we moved to the back of the Mayor's house where a Middendorff's Grasshopper-warbler surprised us when it briefly popped out from the grass providing a millisecond clear vie. Arctic (Kamchatka) Warblers called from the acacia trees.



It was definitely worth the short trip!  Unfortunately, our previous appointment did not allow us further exploration so we started driving back.  We drove slowly, trying to take photos of the very common Red Turtle Doves foraging on the ground and the Pied Bushchats which patrolled the dirt road.





We were pleasantly surprised to find a few waders at the muddy, unplanted fields.

There were a few Little Ringed Plovers...



...and several Long-toed Stints...



... and some Wood Sandpipers.



A lone Little Egret was wiggling his foot in the water.



They didn't seem to mind us as we took our photos.  Every now and then a group would be startled and would take to the air and we would be surprised that there were more of them on on the ground than we thought!

They drab winter plumage camouflaged them perfectly with the muddy ground and even as they moved about looking for food, it was difficult to spot them.

How many stints can you see in this photo?


Much as we wanted to linger and stay, it was fast approaching noon and we had to move on. I hope to be back several more times before the summer!
