Morton Arboretum produced blue grosbeak, lark sparrow
and pileated woodpecker.
Finally, we hoped to provide ecosystem managers with information that could help them restore savannas in a way that would enhance the bird community, specifically increasing overall species richness and abundance of birds that utilize snags, including some uncommon or threatened species, such as the Red-headed Woodpecker (Melanerpes erythrocephalus) and the Lark Sparrow
Due to sample sizes of nests, we could only justify comparing Mayfield nest success rates for Cassin's sparrow, grasshopper sparrow, and lark sparrow
. Cassin's sparrow nest success during this study ranged from 0.202 on unburned sites in 2007 to 0.529 on burned sites in 2007 (Fig.
These birds have earned the unfortunate distinction of a spot on Audubon's list: American Bittern, Black-throated Sparrow, Boreal Chickadee, Common Grackle, Common Tern, Eastern Meadowlark, Evening Grosbeak, Field Sparrow, Grasshopper Sparrow, Greater Scaup, Horned Lark, Lark Sparrow
, Little Blue Heron, Loggerhead Shrike, Northern Bobwhite, Northern Pintail, Ruffed Grouse, Rufous Hummingbird, Snow Bunting and Whip-poor-will.
Bachman's sparrow, lark sparrow
, Bewick's wren, Cerulean warbler, Swainson's warbler, Bell's vireo, and Mississippi kite represent some of the rare but nongame species of birds in the area.
Some highlights of the 2006 Survey include the observations of a Baltimore oriole, a rose-breasted grosbeak, and a brown thrasher in Arviat, a yellow-headed blackbird north of Wrigley, and a lark sparrow
in Colville Lake, as well as the discovery of an American robin's nest in Rankin Inlet.
The depression of driving through the night to Norfolk and arriving to find the American lark sparrow
had continued its journey before we finished ours.
The 11 most abundant birds seen during summer surveys on Aquilla Lake included northern bobwhite (Colinus virginianus), northern cardinal, Carolina chickadee, yellow-billed cuckoo, dickcissel, killdeer (Charadrius vociferus), lark sparrow
(Chondestes grammacus), eastern meadowlark, northern mockingbird (Mimus polyglottos), mourning dove and painted bunting (Passerina ciris).
The degradation, displacement, and fragmentation of coastal prairie habitat has contributed to the decline of such birds as the lark sparrow
(Chondestes grammacus), Henslow's sparrow (Ammodramus henslowii), LeConte's sparrow (Ammodramus leconteii), Attwater's greater prairie-chicken (Tympanuchus cupido attwateri), and other grassland-dependent bird species.
to 10 Aug., 2009: White-eyed Vireo (Vireo griseus; Hopp et al., 1995), Blue-gray Gnatcatcher (Polioptila caerulea; Kershner and Ellison, 2012), Northern Cardinal (Cardinalis cardinally, Halkin and Linville, 1999), Painted Bunting (Passerina ciris; Lowther et al., 1999), and Lark Sparrow
(Chondestes grammacus; Martin et al., 2000).
we included the ash-throated flycatcher (Myiarchus cinerascens), western kingbird (Tyrannus verticalis), warbling vireo (Vireo gilvus), Lucy's warbler (Oreothlypis luciae), western tanager (Piranga ludoviciana), chipping sparrow (Spizella passerina), lark sparrow
(Chondestes grammacus), lark bunting (Calamospiza melanocorys), black-headed grosbeak (Pheucticus melanocephalus), lazuli bunting (Passerina amoena), Bullock's oriole (Icterus bullockii), and lesser goldfinch (Carduelis psaltria).
We observed one species of conservation concern (USDI, 2002; Rich et al., 2004; Butcher et al., 2007) in WCSP (bobolink, Dolichonyx oryzivorus, n = 16), two in commercial sunflower (bobolink, n = 31; northern harrier, Circus cyaneus, n = 1) and two in non-sunflower crop fields (Franklin's gull, Larus pipixcan, n = 1; lark sparrow
, Chondestes grammacus, n = 10) during point counts.
