COBirders,
I made a quick stop at Big Johnson Reservoir today (~10:00 am) to see what
might be there before the storm hit. No water coming in now so this cold snap
could finally freeze it up for a while. There were many Northern Shovelers and
Pintails, very few of any other species of duck. The gulls were few, 93 total
that I could tell for sure. There was one bunch tightly packed at a distance
so not sure how accurate the count was but only +-5 birds would be my guess.
The interesting part was the ratio of gulls.
3 Lesser Black-backed Gulls (all adults)
22ish Ring-billed Gulls (all adults)
68 Herring Gulls (all but 1 were adults)
There could have been a few more Herring Gulls in the tightly packed group but
I just could not tell. About 30 birds left around 10:15 am and appeared to
head towards a dump that is southeast of Colorado Springs. The other group
left about 15 minutes later but I failed to see where they went as I was busy
picking through the Canada Geese. I would bet the reservoir will still have
open water tomorrow but anything beyond that I somewhat doubt unless the wind
picks up again.
