I wasn’t having much luck finding birds on an early morning walk at Ashbridge’s Bay.

The exception was Kingbirds:

Then I noticed a small bird moving erratically and briskly through some middle-level tree branches:

I like my grandfather, Dr. J. Murray Speirs’, description of the Blue-gray Gnatcatcher in his Birds of Ontario: Everything about this restless sprite spells excitement, constantly flitting about, fanning and cocking its tail, uttering high-pitched squeals like a high soprano catbird, busily gathering lichens and spider webs to decorate its two-inch cup-shaped nest.

But do they catch gnats?

Here is the diet description from the Cornell website: All About Birds:

Adult and larval moths can provide up to half of prey taken. The smallest prey are swallowed alive. The wings are torn off larger prey and their bodies beaten on a perch prior to being eaten. Parents generally feed the young these same foods, offering progressively larger whole prey as the chicks mature.

To answer the “gnat” question:

A gnat is a loose descriptive category for any of many species of tiny flying insects (Wikipedia)

With that definition, they certainly do catch and eat gnats.

NATURE POETRY

Warm summer sun,
    Shine kindly here,
Warm southern wind,
    Blow softly here.
Green sod above,
    Lie light, lie light.
Good night, dear heart,
    Good night, good night. - Mark Twain
