First birding day in a while!

An open space with a sign that reads "Keep physical distancing"

After almost six months of confinement due to the sanitary emergency, I finally went out to have a birding day, searching for shorebirds in order to participate in the World Shorebirds Day.  The high tide was quite early, so I started with the first lights.  My plan was to visit several places along the waterfront of Panama City, following the tide.  With the water level high, I chose a rocky spot that provide resting sites for tired shorebirds when they are not foraging in the mudflats.  As expected, I found some loose flocks with some of the most common species, plus rocky shores specialists, like Ruddy Turnstones and Surfbirds.  However, they were too distant for decent photos, so I concentrated my shots in some nearby targets, like the groups of Least, Semipalmated and Spotted Sandpipers that were checking the small puddles on the rocks.

After 30 minutes carrying my backpack, camera, lens and binoculars, I realized that I was exhausted!  Certainly, the sedentary routine of my confinement had something to do with that!  The air conditioner of my car was huge relief... but I had no time to waste, the tide was retiring, exposing the mudflats of my next stop: Costa del Este.  The wetlands of the Upper Bay of Panama are of hemispheric importance for the migratory shorebirds.  Millions of birds use the area during their annual paths, the reason why Panama Audubon Society has worked incessantly in protecting the site, monitoring its birds and doing environmental education in the surrounding communities... and Costa del Este is one of those communities.  From the lookout with interpretative signs depicting shorebirds, I was able to scan the extensive mudflats at the mouth of the Matía Hernández river, adding Black-necked Stilts, Black-bellied Plovers, Greater Yellowlegs, Short-billed Dowitchers and, specially, thousands of Western Sandpipers, although widely dispersed.

After my short 30-min stop at Costa del Este, I went to a nearby site for a change.  If you want to see a greater diversity of species, then you need to visit different habitats, so I went to a grassy meadow with artificial ponds, known as MetroPark.  The pond had Wattled Jacanas, Black-necked Stilts and both Lesser and Greater Yellowlegs, while the grassland had Whimbrels and many Southern Lapwings.  I was not the only human being at the site, several people use the open spaces to work out and breath "fresh air"... of course, following the sanitary recommendations, as explained in the multiple signs all over the place (as you can see in the first photo).  My last stop was, again, a different habitat... the only sandy beach of the waterfront, right at the Panama City's coastal belt, by the mouth of the Matasnillo river.  As expected, it produced my only Sanderlings of the day.  Two pale birds were agitatedly feeding in the sand, going forth and back with the waves.  By that time, the tide was low enough to take a break until the next high tide, in the afternoon.

For the second round, I joined my friends Rosabel Miró, Venicio "Beny" Wilson and Aitor Gonzalo, who were also participating in the World Shorebirds Day.  We were after an species that occurs near the city only at one reliable site at the West Bank of the Panama Canal.  The combination of sandy and rocky beaches with tons of bivalves and other mollusks to feed is ideal for the American Oystercatcher.  we knew a place where they breed, so we went there and were rewarded with a pair of vocalizing birds that flew right above us... what a sight!

Pitifully, we were not able to find two plovers species that are also found at that habitat: Collared and Wilson's Plovers, which are also localized near the city.  To take advantage of the few hours of light left, we swiftly moved back to Costa del Este, where the tide cornered the birds in a section adjacent to the mangroves, where these birds spend the night.  We added Marbled Godwit to our checklists, but were impressed with the thousands of peeps present at the site, mostly Semipalmated Plovers, Western and Semipalmated Sandpipers.


Almost at night, we left the mangroves (and the mosquitoes), our final count was more than 5000 peeps in that little corner of mangroves.  At the end of the day, I managed to record 19 different species of shorebirds at, or near, Panama City.. an excellent number!  So tell me, how was your World Shorebirds Day?

Hungry birds

The exposed mudflats, mangroves and beaches of the Upper Bay of Panama are a very important feeding station for both migrant and resident waterbirds and waders year-round.  The simply amazing numbers of peeps and other shorebirds that spent most of their lives here are prove of that.  But this time, I want to highlight that almost during every visit I witness a waterbird catching/eating large catfishes... like this Great Egret in Costa del Este.
Great Egret
The habitat is just ideal for the catfishes, so I guess they abound and are quite easy to catch. Sometimes, the birds just take them from the mud... or, in the case of the Magnificent Frigatebirds, are stolen from other birds.  This is a repetitive scene in Panama Viejo (where I took the next photos): a lucky bird catch a fish just to be harassed by these feathered pirates... and who can resist those bandits?
Magnificent Frigatebird
The Magnificent Frigatebird is a specialized kleptoparasite... parasiting by theft.  However, as it usually happens, this frigatebird was not the only one patrolling the site and soon another individual tried to steal the prize.
Two Magnificent Frigatebirds after the fish
Seeing those two frigatebirds in the air is fun.  The large birds are extremely agile in the air, and elegant... even when they chase each other.
Agility in the air
Eventually, the catfich fell to the floor... after all, nobody knows to whom is working... the birds spend 10 minutes disputing the catfish just to give it to a cat that was just passing by.
Yummy!
What can I say?  Some are luckier than others!

World Shorebirds Day

Today, september 6th, is the World Shorebirds Day... and to celebrate it many people around the world is censing its local population of shorebirds in more than 750 selected sites.  Panama was not the exception.  In order to include the general population, NGOs and public institutions, the Panama Audubon Society (PAS) organized the "Shorebird Challenge" at the registered counting site in Costa del Este (Panama City).
PAS Executive Director, Rosabel Miró, listed the rules for the challenge.  Simple: each organization would be represented by 4 members (plus supporting staff) and provided with binoculares and illustrated field guides with the objective to ID the greatest number of shorebirds species with no professional aid (all these participants were non-experienced in the theme of birdwatching) in 30 minutes.  Each team was assigned an "expert" birdwatcher in charge of the checklist.  We weren't supposed to help in the ID  of any species.... just to confirm it.  All the "experts" were PAS members.

The team of the Capital District Municipality, guided by Venicio, were the undisputed winners, identifying 11 shorebirds species after sticking to its strategy of "being where the birds are"... they changed its original watching site after quickly recognizing that most of the flocks were in the other side of the river!  Good one!
1st place: Capital District Municipality team (11 species)
My own team, the crew of MarViva, a regional NGO that promotes the conservation and sustainable use of coastal and marine ecosystems in the Eastern Tropical Pacific, correctly identified 9 shorebirds species.  Our strategy was pretty the same of "being where the birds are"; however, we spent all the necessary time pointing out field marks and didn't make it to the other side on time (where a huge and diverse flock was resting).
2nd place: MarViva team (9 species)
Two teams identified 8 shorebirds species.  The draw was resolved by a knowledge test that won the team of the National Environmental Authority (ANAM), guided by Ariel Aguirre.
3rd place: ANAM team (8 species)
Leaving then in the fourth place (also with 8 shorebirds species identified) the composite team of several NGO's and government agencies, including members of Panama's Aquatic Resources Authority (ARAP), Ramsar CREHO and Wetlands International. The last team, the representatives of the Ministry of housing and land zoning (MiViOT), identified 7 shorebirds species.  As you can see, all the government agencies and NGOs that participated have something to do with the protection of the habitat that these shorebirds need in the Upper Bay of Panama.
4th and 5th place: ARAP/CREHO/Wetlands and MiViOT teams
What a great experience.  As mentioned earlier, the site was full of shorebirds and other aquatic species... but the activities are not over... and I will show you some of the shorebirds we managed to ID in another post!
