Weekend Slough Sightings

This was sent in from a slough visitor…  Feel free to leave comments on bird ID.

Hi,
We saw the flamingo on our Elkhorn Safari tour.
I have attached the photo.
Also, during our hike at the Elkhorn Preserve we saw a Hummingbird and an unidentified bird (Chickadee??).
I was wondering if you can identify them (which kind of Hummingbird?)

Thanks very much,
Barna De
