“EMERALD EYES”: NEOTROPIC CORMORANTS ON ABACO

Neotropic or Olivaceous Cormorants Phalacrocorax brasilianus. Smaller cousins of the familiar double-crested cormorant, and occupying a quite different range. In the northern Bahamas they are considered to be uncommon summer residents whereas the big guys are common year-round residents. However the neotropics’ range has spread in the last decade and they may become more noticeable on Abaco. Right now, Abaco is pretty much the northern boundary.

In many ways, cormorants are taken rather for granted – ubiquitous black guardians of the coastal margins. But seen close-to, they have their glamour. This is especially true of the slimmer neotropics, with precious jewels for eyes and intricate plumage patterns that a mere fly-past cannot reveal.

Besides being smaller and lighter than the double-cresteds, these cormorants have longer tails. They are mainly fish-eaters both at sea, and inshore where ponds are to be found. They make brief dives to find food; in groups they may combine to beat the water with their wings to drive fish into the shallows where they can be picked off more easily.
