Hi Kris,
Sad I missed out on the Black-crowned Night Heron. That remains on the missing list for me for the year. As for the Bank Swallows, I do in fact have a picture from my junky Wal-Mart camera, which shows the diagnostic breast band quite well, as I caught one perched on a branch at close range, face on (and admittedly assumed the other individual was the same). That being said, coming from Newfoundland, that would be a lifer for me, and I certainly do not preclude the possibility that I made a mistake given my inexperience with the species, and the inordinate amount of difficulty I have in identifying swallows generally for the fairly modest identification problem they pose. Only problem: I'm not sure how to upload it here. Please let me know how to do so (or I can PM you, if desired) and we can consult. EDIT: Just noticed the stickied thread about posting images. Will attempt that later.
Also, MC, glad I could help! I actually spent 20 minutes or so today studying some of the less commonly used field marks today on a couple of individuals hanging about the marina, as I have much to learn too. Hope we can get out birding again soon some day!
All the best,
Doug Clark
