Avian day

Observations from a day driving around Cook County...the morning started with a common yellowthroat in our next-door neighbors' front yard...the great blue herons are back on their nests at Busse Woods, where you can see a rookery from I-90...I saw three turkey vultures soaring low over Paul Douglas Forest Preserve...The Cook County Forest Preserve sites in the Northwest Suburbs are a new frontier for me. There is also an extensive swampy area at Arthur Janura Preserve that looks promising...I saw an american kestrel dive onto something right off I-90...a pair of mute swans have taken up at an office park pond just north of I-90 near Schaumburg...three white-tailed deer were sitting in a highway easement just east of O'Hare...I heard a white-crowned sparrow call outside a church in the East Garfield Park neighborhood on the city's West Side...at the same church, house sparrows were clinging to the building's stone walls. I don't know why they do this...
