Tiny Swarming Gnats

April 22, 2019 – Gnatcatchers, warblers, kinglets and wrens were feeding on the abundance of tiny swarming gnats this past week at the edge of a small wooded area south of Kankakee. There were five Blue-gray gnatcatchers quickly hopping from branch to branch feasting on the large number of gnats that were covering the tree branches. The gnatcatchers are migrants that winter from the Southeastern coast of the United States, Florida, along the Gulf coast west and down into Mexico and Central America. Northern Illinois is near the northern edge of their nesting range that stretches up into Wisconsin and may be expanding as the climate warms.

A Northern parula warbler studies the bark of the tree looking intently for a small insect.

A pair of Ruby-crowned kinglets were visiting the same tree taking advantage of the abundance of protein. The little kinglets are about halfway between their winter range and their summer nesting territory. A house wren was also at the banquet and is now in its’ summer range while the smaller Winter wren that was busy searching for insects lower on a tree stump still has a little ways to go before it reaches its’ summer nesting territory. Field sparrows were there looking through the nooks and crannies of the decaying wood stumps for insects and worms.

A Northern parula warbler which nest in most of the eastern half of United States brought the most color to the brunch. The small parula warbler is a long-distance neotropical migrant that winters along the Gulf of Mexico from Mexico down into Central America and east throughout the Caribbean. The tiny warbler has yellow from under its’ chin down across its’ breast. The lower half of the birds bill is a bright yellow that matches those bright yellow feathers on its’ chin and even in the muted light looked brilliant against the bluish feathers on the upper parts of the little warbler.
