A Bit of This and That:

A White-throated Sparrow has chosen to spend the winter in Canatara Park. I have seen it several times, but Deryl was able to photograph it when it popped up and posed for him. White-throated Sparrows tend to stay near the ground, scratching through leaves in search of food. You may see them low in bushes, particularly in spring when they eat fresh buds.

White-breasted Nuthatches get their common name from their habit of jamming large nuts and acorns into tree bark, then whacking them with their sharp bill to "hatch" out the seed from the inside.  https://www.allaboutbirds.org/guide/White-breasted_Nuthatch/overview

Many gulls, including these Greater Black-backed Gulls took a break on the ice in Sarnia Bay, when we actually had ice. It is the largest Gull species in the world, weighing up to 4.5 pounds with a wingspan up to 63 inches!

More often than not, the Sarnia Bay has been free of ice this winter. Mallards enjoyed the "surfing" conditions on the choppy water one day.

The white bird in the centre of the photo is a Ross's Goose. Like the Snow Goose, it is also white with black wingtips but has a shorter neck and stubbier bill. A Ross's Goose can often be picked out of a large flock of Snow Geese by its immaculate white head. Snow Geese usually have yellow staining on their heads because they eat tubers in marsh soil. Ross's Geese tend to forage more on plants at the water's surface.

In their never ending quest to access our backyard bird feeder, a squirrel has been unsuccessfully launching itself from our daughter's day camp craft, made oh so many years ago.
