Seedeater Birdscapes
April 20th, 2014
The
seedeaters, as a
group, stole my heart in Costa Rica. No, they're not colorful or beautiful
singers or anything like that, just very small and shy and cute. They seemed
to me as tiny as hummingbirds. The sapling palms near our resort were dripping
with them.
A close-up was out of the question. As soon as I approached within a certain
distance, every last one of them would melt into the scenery. I had to make do
with "birdscapes." I especially liked the view of these female Yellow-Bellied
Seedeaters with the mountains silhouetted in the distance.
Top to bottom: male Yellow-Bellied Seedeater, female White-Collared Seedeater,
juvenile male Yellow-Bellied Seedeater, male White-Collared Seedeater. (Yes,
there's a fourth one hiding down there.) Yellow-Bellied Seedeaters roam widely
in search of seeding grasses, and apparently that's the only reason I saw
them. They're not normally found in Quepos. Johan Chaves went searching for
them after I left, but the flock had already moved on.
Equally tiny Blue-Black Grassquits shared the same habitat. These guys were
quite pretty when the light caught them and revealed their cobalt-blue
iridescence. They were also more amenable to close-ups.
Many scientists believe that Blue-Black Grassquits were the original parent
species of
Darwin's
finches--the birds that helped Charles Darwin develop his theory of
evolution. When they first spread to Galapagos the islands were nearly
birdless. So they proceeded to rapidly diversify into about fifteen different
species, each one exploiting a previously empty niche.
A pair of Mangrove Black Hawks was nesting in a big dead tree near the
estuary. These hawks' favorite food is crabs, sometimes captured by racing
after them on foot through the mud! To everyone other than crabs, they seemed
to hold the status of "gentle giant"--the little seedeaters would perch in the
same tree as them without any sign of fear. The hawks also tolerated me close
to their nesting tree, although the first time I walked by on any given day,
one of them would usually do a quick fly-by to check me out (or maybe dissuade
me from trying any funny business?) This made for a good photo op if I had my
camera at the ready.

Really like the composition of the first pic!
