Re: Field Trip to Southside Water Treatment Plant
Naturally, many other birds will be worth studying. These species strike me as the most obvious identification problems. You are encouraged to review the checklist of Southside ahead of time.When referencing shorebird images, please note the dates of the images. August birds are likely in a state of prebasic molt. Winter plumages and breeding plumages are very different. Even in August, birds like Western Sandpiper are changing their plumage by the day in late August.
Specific information on this subject can be found on page 77 of Kaufman's Advanced Birding (newer edition).
A nice illustration of molts in shorebirds as an example (these birds are from Europe, but the idea is relevant).
Also, please note the most widely used website for hearing the calls and songs of all birds ... xeno-canto ( http://www.xeno-canto.org ). You can search for species in the search box at the top of each page.
One of the best comparative references on shorebirds is Kenn Kaufman's Advanced Birding, but all of the field guides and most books on shorebirds can be of some help.
Please make sure to download the checklist for Southside WTP here (hat tip to Chris Runk and Dell Little).
