This week’s species dossier covers my observations of our only eastern hummingbird, the ruby-throated.
1986. To this point I have seen hummingbirds in the Culver, Indiana, area, near Jeffersonville, Indiana, in south central Pennsylvania, once in fall migration at Ann Arbor, Michigan, in Maryland on the Delmarva Peninsula, and in Virginia. They visit flowers, especially bright orange or red ones including trumpet creeper, cardinal flower, and jewelweed. They are occasional migrants at Willowbrook Wildlife Center, DuPage County, Illinois. They seem to require forests or woods edges.
15SE87. Young or female hummer (dark stripes on pale throat) feeding from orange jewelweed, midday, Willowbrook.
27JL99. Hummingbird made brief appearance near Willowbrook picnic shelter.
22AU99. Hummer on jewelweed at West DuPage Woods Forest Preserve.
8&17SE99. Migrant hummers at Willowbrook.
8MY00. Arboretum. At parking lot 23, a hummingbird nest, perhaps still under construction because it is pale and obvious, well out from the trunk of a tamarack on a horizontal branch 20 feet up.
15JE00. Arboretum. At Parking Lot 23, hummingbird female is on the nest, which does not stand out as much as last week (outer surface has more material added).
17JE00. Arboretum. The hummingbird female leaves the nest frequently, perhaps for 30 seconds every 5 minutes.
16JE01. Arboretum, Heritage Trail. Many scattered fire pinks are flowering, and a hummer was visiting one of them briefly, then moved on.
22AU(year not indicated). West DuPage Woods. A hummingbird on jewelweed.
2AU04. An immature or female hummingbird visited the royal catchflies in my back yard flowerbeds.
21JL06. An immature or female hummingbird at back yard royal catchflies.
15JL09. First immature or female hummer visiting the first royal catchflies, also bergamot and the last white wild indigo flowers.
