[EBB Sightings] Lake Merritt, Oakland - Sunday 20 Feb 2010 - Tufted Duck, Common Mergansers, Green Heron, Ospry etc.

Today I took my Ornithology class to Lake Merritt in Oakland.  We added
three new species to our cumulative list going back to 1985:

Common Merganser
Green Heron
Osprey

There were at least five Common Mergansers all in female plumage except one
immature male.

The adult Green Heron was on a pipe between the islands.  Photo at:

An Osprey flew over around 9AM, chased by a Glaucous-winged Gull. 

We also saw the over-wintering male Tufted Duck at the duck feeding area.
