Phenology Calendar

Posted by Wayne G. Barber

Fourth Week of July



Earthworms make up 15-20 percent of a robin's summer diet. Many worms are plucked from mowed lawns where the robins can more easily see them.

Crows may be getting help in raising their chicks from last year's offspring.

Sharp-shinned hawks eat small birds, averaging about one per day.



First Week of August



The lovely song of the hermit thrush may still be heard. Most other birds have stopped singing.

Milk snake eggs that were laid in the spring are hatching.

Large dragonflies such as the green darner (Ajax junius) may replace flying with some gliding on hot days to prevent overheating their flight muscles. Source: Northern Woodlands, Virginia Barlow
