Here is a different one ...
Back in winter last year I discovered a strange-looking chickadee at a Provincial park not too far from Saskatoon.
The park is a haven for Black-capped Chickadees, that are actually very used to humans and allow us to feed them by hand. Most of the chickadees here don't care if you have food or not, half the time, and will readily try to land on you regardless!
It was at this park I noticed an unusual looking bird, that looked like a Black-capped Chickadee, but had a thin white eyebrow stripe above both its eye's.
Luckily I documented this bird with a couple of photos, and the general consensus was that this bird was a possible hybrid between a Black-capped and a Mountain Chickadee.
2 days ago I was able to find the bird again, or should I say , it found me !
More information on chickadee hybrids is here in this small article :
