Prothonotary Warbler Nestling Growth Guide

This is a guide to help people identify the age of Prothonotary Warbler nestlings in a nest box. I hope it helps promote the Prothonotary Warbler conservation effort.

Papa Prothonotary Warbler

The male Prothonotary Warbler followed the female to the nest box and remained at the entrance to check on her and the four chicks while she fed them.

Prothonotary Warbler Nesting from 2012

This nesting took place in May of 2012. It took place in a Gilbertson PVC box. The photos start with the female gathering nesting material, the male visiting the box, egg laying, hatching of eggs, after several days of growth of the nestlings and finishes off with a nestling peeking out of the box just before it fledges.

A few photos from the Prothonotary Warbler nesting.
