Red-necked Grebe Nest: April 2021

On a morning of off-and-on rain, I headed to Humber Bay.

The most obvious birds were the hundreds of Cormorants in the sky and in the lake. These are eerie birds as they are completely silent.

Humber Bay, Col. Sam Smith Park and Tommy Thompson Park all provide floating nesting platforms for Red-necked Grebes.

The grebes at Humber bay have constructed a nest of twigs, reeds, aquatic vegetation, bark and even some plastic:

The female Red-necked Grebe lays two to six eggs which hatch in about three weeks.

Grebe chicks have striped heads:

Both parents care for the young.

The red-necked grebe eats minnows and other small fish, crayfish, tadpoles, salamanders, insects, and aquatic plants.

Gadwalls have a white patch on the rear end of the wing. Males have a black rump as this one does.

NATURE POETRY

Again the blackbirds sing; the streams
Wake, laughing, from their winter dreams,
And tremble in the April showers
The tassels of the maple flowers.        – John Greenleaf Whittier (1807–92)
