THICK-BILLED VIREOS ON ABACO: “NIDIFICATION”

“Nidification” was one of the new words I learned from the wonderful book Birds of the West Indies by James Bond (a different one – for the full story behind the name click HERE). It means, essentially, the nesting process of a bird. It sounds pleasingly technical for a straightforward concept: nest-building.

I spotted this TBV making its nest on the edge of the drive at Delphi. I usually think of these cheerful chirpy birds as ‘lurkers’, hanging back in the coppice and not making themselves easily visible. But this nest was right out in the open – possibly not the wisest place for nidification.

If you look up TBV’s in bird books, you may find a reference to nest building in the fork of shrubs or bushes – exactly what was going on here. It quite a messy nest, but then again it looks comfortable and firmly wedged in.

Although I only saw one of the pair actively engaged in the building, another TBV was ‘vocalising’ (there’s another technical term, = singing) nearby, presumably the mate. In a way that humans have been slow to adopt, both birds will be actively involved in raising their family, from incubating the eggs to chick care – feeding, cleaning out the nest and so on. 

WHAT DO THEY SOUND LIKE WHEN THEY VOCALISE?

Let’s hope for a successful outcome to the nidification…
