Last month, Kleen rushed to a backyard in the Springfield area where he successfully banded a broad-billed hummingbird
, only the third one ever documented in Illinois.
Across all sites flower visitation with potential or evident pollen transfer was observed by native bees (predominantly Halictidae) (265 focal individuals), honeybees (Apis mellifera) (23 focal individuals), and hummingbirds (Anna's hummingbird, Calypte anna, broad-billed hummingbird
, Cynanthus latirostris, and black-chinned hummingbird, Archilochus alexandri) (37 focal individuals).
The birds caught yesterday were all ruby-throated hummingbirds, although six species of hummingbird have been seen in Massachusetts, including a broad-billed hummingbird
seen for the first time last year on Cape Cod.
In one extreme, bird species such as the Broad-billed Hummingbird Cynanthus latirostris, the Great Kiskadee Pitangus sulphuratus, the Blue-grey Gnatcatcher Polioptila caerulea and the Streaked-backed Oriole Icterus pustulatus were mainly found in Acacia forests (Table 3).
The Broad-billed Hummingbird, the Rusty-crowned Ground-sparrow Melozone kieneri, the Canyon Wren and the Sinaloa Wren Thryothorus sinaloa were commonest in the first habitat in the first year but birds such as the Streaked-backed Oriole, the Ladder-backed Woodpecker, the Blue Grosbeak Guiraca caerulea, the Goden-fronted Woodpecker and the Empidonax Flycatcher favoured the two habitats in the two springs (Table 4).
The two species with higher probabilities for Acacia forests were the Broad-billed Hummingbird and the Great Kiskadee, particularly in autumn (Fig.
the broad-billed hummingbird favoured Acacia forests while the Curve-billed Thrasher favoured Acacia and Ipomoea forests in the four seasons, while the Streaked-backed Oriole and the Yellow-breasted Chat were either ubiquitous or unpredictable in autumn but favoured Acacia and Ipomoea forests in spring).
The broad-billed hummingbird
(Cynanthus latirostris) is found along the bases of canyons and small streambeds.
