Steve N. G. Howell's "Gulls of the Americas" is an excellent book, with a
few pages of pics per species, including various ages, birds in flight,
resting, etc.

Hi Deb
Not familiar where Denver gulls move around to ... but your choices make sense
they like big open areas to roost.

I’ve seen amazing numbers of gulls flying north to south near Littleton, Platte
Canyon and Bowles, at sunset. Going to Chatfield? South Platte reservoir?

Jared,
Colorado's own John Vanderpoel has produced two excellent videotapes for
gull study,
one for large gulls, the other for small (The Small Gulls of North
America). I learned a lot
watching them, and you will too. They are not difficult to find on line by
searching his name and that title.
Hi Jared
Could not find a "gull in flight ID guide" but found these useful PDFs
about gull ID:

- This book is excellent:
