Found a couple of groups of Gulls in Agassiz over the past 2 days. Unfortunately, digiscoping screws with the colours... but I hope to get a bit of help.
Around Mountainview Rd. and Agassiz Ave were about 200 - 300 Gulls, mostly Mews and Glaucous-winged.
I spotted this guy. The wingtips were dark. I'm thinking Glaucous-winged hybrid, probably crossed with Western.
The bird on the left had grey wingtips and seemed to be a normal GW, but the bird on the right had dark close to black wingtips (despite the photo) and a small more delicate looking head and body. Is this perhaps a Thayer's? Or is it another hybrid, perhaps female explaining the smaller size?
This was another dark wingtiped individual, with the fierce look of a GW/Western Hybrid.
In amoungst the Mews, was this one. I've been fooled by rings on bills before, but this one stood out. Ring-billed?
At the end of Limbert Rd., the gravel section outside the dyke, the Western Grebe is still hanging around, with a few Trumpeter Swans and Canada Geese, about a hundred Mallards and over 500 Gulls. The Gulls were mostly Mews with a number of GWs and a few big dark wingtip unknowns.
On the left, much cleaner headed and the bill seemed more delicate than the smudged headed adult on the right. Both had dark wingtips, so both hybrids?
Here I got a GW with nice grey wingtips next to Hybrid? with dark wingtips. The possible hybrid seems a bit different to me and I don't know why, but I keep thinking Herring?
Another smudged head GW/Western Hybrid.
thanks for having a look...
