Wader Frenzy At WSR

A collection of waders, mostly heron and egrets, feeding at WSR

The dry season brings many ponds and wetlands that depend on rainwater to the brink of drying up. The water retreats and leaves behind the numerous creatures, fish, tadpoles and insects that dwell there, exposed. They are easy targets for the wading birds, such as herons and egrets, who swarm in masses to dine on them. This yearly phenomenon, if witnessed, can be a marvelous experience for nature lovers. I got the opportunity to see it this year at the Woodbourne Shorebird Refuge (WSR) and it highlighted why Barbados, though not the most birdy places on earth, is one of the most unique birding locations in the Americas. How so? Because it is one of the few places where you can commonly observe new world and old-world versions of some bird species.

Among the many white egrets busy feeding, a discerning eye could distinguish the Snowy Egret (Egretta thula) and its old-world counterpart, the Little Egret (Egretta garzetta), in the mix. To spot the Snowy Egret, an indigenous bird of the Americas, one only has to look for the bright yellow skin that separates the eyes and the bill, the lores, and its shaggy head crest. Its cousin from across the ponds, the Little Egret, which arrived on this island in the mid 50s, has much paler lores and a more neat and uniform double or single plume coming from the back of the head.

Another such and even rarer example of new and old-world versions of a species living side by side naturally was that of the Great Blue Heron (Ardea herodias) and its old-world cousin the Grey Heron (Ardea cinerea). These two are even more challenging to tell apart, and I must admit I am still learning the differences between these two species. One field marking that I do look for is the color of the thighs. The Great Blue Heron’s thighs are brownish while the Grey’s ones are always pale.

Little Blue Heron

While these were some of the more interesting species in the frenzy, they were not the only ones. Continuing in the heron family, there were a few Green Herons (Butorides virescens), Little Blue Herons (Egretta caerulea) and also, as it got later in the evening, two Black-crowned Nightherons (Nycticorax nycticorax) joined the mix. From the egret side of things, there was the ubiquitous Western Cattle Egret (Bubulcus ibis) and Great Egret (Ardea alba), a bird which is common on both sides of the great pond. In total, eight species of egrets and herons were on display at the WSR, feasting on the critters trapped by the receding water level.

It was a sight to behold and one I am glad to share. Stay safe and enjoy your birding.
