Can someone post a picture of a SY and ASY female? I think I can tell the difference but am not sure.

Hi Harold,

Its tough to age females, but I mostly go by the appearance of the underside of the tail - an area called the "undertail coverts".

PMCA has an excellent Update magazine article on determining age and sex of martins. Click on:

Thank both of you for your reply. I wasn't sure how much difference there was in each one of them.
