Gray Catbirds (GRCA) are still wandering south and this is a good opportunity to see the coverts on a hatching-year (HY) bird. Hatching-year secondary and primary coverts are edged with brown while the adult will be clean gray. By spring time most HY birds will have worn this brown edging off but there are a few that may still show some remnant of it and can then be called second-year (SY) instead of the usual after-hatch-year (AHY). Aging a bird AHY only tells you it was born prior to the previous calendar year. It is important that banders age each bird as definitively as possible to improve the knowledge of the demographics of the populations migrating through the area.
|Adult GRCA: Note gray edged primary and secondary coverts.|
This bird also had some white feathers under its chin where it is normally gray on GRCAs

Another treat of the week was the female GWWA that graced the station. Thanks to volunteers Ryan Jacob and Don Bauman for providing the photos.
