meadowlark

For Eastern Meadowlarks, Grasshopper Sparrows, and Dickcissels, as the focal grassland songbirds, and Brown-headed Cowbirds, their brood parasite, we estimated densities separately by species.

Repertoires, territory size and mate attraction in western meadowlarks.--Condor 97: 1080-1083.

We used flushing transect-surveys to sample species that were relatively easy to identify when flushed: northern harriers (Circus cyaneus); horned larks (Eremophila alpestris); Sprague's pipits (Anthus spragueii); vesper sparrows (Pooecetes gramineus); eastern and western meadowlarks (Sturnella magna and S.

The most abundant species were grasshopper and Henslow's sparrows as well as eastern meadowlarks (Sturnella magna) and red-winged blackbirds (Agelaius phoeniceus).

CRP fields used by eastern meadowlarks and bobolinks were significantly larger than nonused fields.

A nearby hilltop meadow full of singing bobolinks, meadowlarks and savannah sparrows is Field Editor Les Line's favorite haunt on blue-sky days in late May.

What will be crucial for us in this new era is to remember that the "federal solution" is more often a meadowlark than a panacea; that there are "ethical and aesthetic premises which underlie the economic system," according to Leopold; and that conservation works only if we each practice it.

This is likely because of the large size of meadowlark chicks and their ability to compete with aggressive cowbird nestlings, or because adult meadowlarks remove cowbird eggs from their nests before they are capable of hatching (Peer el al., 2000).

Of special note is the addition to this highly recommended picturebook for children a very special educational section, 'For Creative Minds', that provides children with fun facts about birds, 'bird math', bird injuries, and a 'Match the Nest' activity with nest information for Magpies, Killdeer, Robins, Screech-Owls, Starlings, Brewer's Blackbird; the Common Grackle, Meadowlarks, Whip-poor-wills, Mourning Doves, and the Northern Oriole.

Grasshopper sparrows (Ammodramus savannarum), eastern meadowlarks (Sturnella magna), red-winged blackbirds (Agelaius phoeniceus), Henslow's sparrows (A.

Sightability functions were developed for meadowlarks as a group.

Our objectives in this study were, thus, to examine topographic effects on the nesting ecology of Dickcissel, Grasshopper Sparrows (Ammodramus savannarum) and Eastern Meadowlarks (Sturnella magna).

Brown-headed cowbirds, dickcissels (Spiza americana), grasshopper sparrows (Ammodramus savannarum) and meadowlarks (Sturnella spp.) were observed more frequently in pastures, and abundances were significantly greater than in CRP fields.

Eastern meadowlarks (Sturnella magna) were the most common nesting species, comprising 71% of nests.
