Plenty To Eat

A Warbling vireo pauses for only a moment as it searches the leaves for insects.

August 5, 2019 – As we are coming to the end of August one can not help but notice the changes that are happening as another autumn nears and summer contemplates its’ well earned rest. The changes that have been a bit subtle are now upon us. The angle of the sunlight brings an inspiring warm tone to the landscape. The gentle breezes swirling through the forest canopy rustles and rattles the matured leaves allowing us to hear those uplifting whispers of the mighty Cottonwood. We have come to that time of the year where there is a bounty in the northern hemisphere for the avian migrants and those birds that are here year-round. Recently fledged birds, along with the adults, are fattening up for the migration, checking every leaf, stem, and branch for insects and worms. Little Blue-gray gnatcatchers, Warbling vireos, and Chickadees are persistently looking over and under every leaf while they cling tightly to the stems as they feed. Thistle and other seeds, berries, and nectar are available for the birds that are coming south from the higher latitudes as well as the birds that have nested here in Northeastern Illinois.

Prothonotary warblers stand out with their bright yellow feathers and olive-gray toned back and wings while gobbling up caterpillars with amazing success as they pluck them off those woody plants at the waters edge. Goldfinches are on the beautiful purple blooming thistle plants along roadways and on the prairies searching for the high fat and protein rich thistle seeds. Adults and this years’ young Hummingbirds stake out and fearlessly defend, from a good perch, their abundant food source, a large thick patch of Orange Jewelweed surrounded by other nectar giving plants. Some of these travelers will be around for a while feeding and fattening-up and growing strong for either a long or short migration. As the weeks go by though, and those abundant food sources in our area start to wane, the north wind bringing cooler temperatures, many birds will leave our area in a final push and continue south where they will spend the winter in a warmer climate.

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.

September 14, 2017 – The Palm warbler is considered a medium distance migrant wintering in the Gulf Coastal region of the United States and the islands of the Caribbean west to the Yucatan Peninsula. The Palm warbler spends the summer on its’ breeding habitat in the low marshy areas of the Northern United State and the fens and marshes in the boreal forests of Canada which is quite appropriately known as “North America’s bird nursery”. The warbler can lay up to five eggs in its’ specialized grass nest lined with feathers and soft plants near the base of a small conifer tree or shrub. One photo shows a Palm warbler in its’ breeding plumage which was photographed in May during the northerly spring migration and the other photo shows a Palm warbler in non-breeding plumage captured this past week in mid September as the little warblers are heading south during the fall migration.
