It is that time of the birding year in Ontario when thoughts turn to the family Laridae (gulls), as reflected by recent posts by others in my blog roll.
I would really like to get in on the action, but I have nothing rare to report (I never do) and no bragging rights to exercise (although there was that Slaty-backed from last year...). Anyway, failing that I thought I would give a personal gull retrospective. All taxonomy is according to The Clements Checklist.
I guess a good place to start is with the numbers. There are 52 species of gull worldwide. I might as well own up that I have personally ticked the following 24:
- Black-legged Kittiwake
- Sabine's Gull
- Slender-billed Gull
- Boneparte's Gull
- Black-headed Gull
- Little Gull
- Laughing Gull
- Franklin's Gull
- Sooty Gull
- Heerman's Gull
- Mew Gull
- Ring-billed Gull
- Western Gull
- California Gull
- Herring Gull
- Yellow-legged Gull
- Armenian Gull
- Thayer's Gull
- Iceland Gull
- Lesser Black-backed Gull
- Slaty-backed Gull
- Glaucous-winged Gull
- Glaucous Gull
- Great Black-backed Gull
As well, gulls like to hybridize and I have observed what I think (or have been told) were the following hybrid crosses:
- Herring X Great Black-backed Gull
- Herring X Glaucous Gull (Nelson's Gull)
- Western X Glaucous-winged Gull
