Bitterns in the City

with one comment

During the last three months I have been making frequents visit to Colombo’s urban wetlands, looking to photograph interesting species and build enough material for an article on birding in these sometimes overlooked spots. The visits follow a pattern of exploring the urban wetlands as places for teaching and learning that highlight biodiversity and urban water issues. I started going more frequently when Colombo’s wetlands started to be better protected several years ago (see the list of past posts below).

Bitterns (Ixobrychus sp.) have been the focus of these recent efforts but I have also been looking to see and photograph other wetlands species. The article has now been completed and awaiting publication-recent tragic events in Sri Lanka have regrettably put on hold the publication. This post shares a few samples of some of the avian highlights.

There are a variety of other species that are associated with Colombo’s urban wetlands.
