Thank you, Mark. Now I
know why I was confused.

HI Margaret,
All your photos are of Welcome Swallows, the first two possibly of juvenile
birds which don’t have tail streamers until they are adult. Adults lose
their streamers when they undergo a post nuptial moult but grow them back
reasonably quickly. Swallows and martins often feed in mixed flocks.
Cheers and Merry Christmas,
Mark

At JWNR today. At first I thought I was shooting
martins of some kind, but when I looked at my shots, some were clearly
swallows. But some were not clearly swallows. Do swallows and
martins feed in mixed flocks? Or do some swallows not have tail
streamers?
