These high-quality areas create a grassland bird community that's home to meadowlarks, dickcissels
, grasshopper sparrows, woodcocks and bobolinks as well as state-endangered northern harriers, short-eared owls and Henslow's sparrows.
Nest searching targeted Eastern Meadowlarks (Stumella magna), Grasshopper Sparrows (Ammodramus savanarnun), and Dickcissels
, as these were the most common grassland nesting songbirds in the area (S.
Evaluation of chemical repellents for reducing crop damage by dickcissels
Similar results were also found when methylanthranilate treated seeds were provided to different birds and similarly when anthraquinone treated seeds were offered to ring-necked pheasants (Phasianus colchicus), red-winged blackbirds (Agelaiusphoeniceus), Canada geese (Brantacanadensis), Dickcissels
(Spizaamericana), ducks and feral pigeons (Columba livia), depredations to seeds significantly becomes suppressed (Avery et al., 2001; Esther et al., 2013; Werner et al., 2009).
Deaderick (1941:209) credited Audubon as being the first to report 50 species of birds from Arkansas, but ignored the Iowa bunting, stating that "several others cannot be placed definitely." Durant and Harwood (1980:180) speculated that Audubon was perhaps referring to dickcissels
(Spiza americana) or one of the longspurs or snow buntings (Plectrophenax nivalis), but these species typically do not occur in Arkansas in winter.
It is possible that enough of these unidentified individuals were grasshopper sparrows, dickcissels
, or meadowlarks, such that any of these species may have in fact been more abundant than brownheaded cowbirds at our study sites.

Fish and Wildlife Service showed that the CRP programs resulted in 1.8 million more grassland birds (e.g., dickcissels
, sparrows, meadowlarks) compared with conventional farmlands.
Yellow-billed cuckoos (Coccyzus americanus) and dickcissels
(Spiza americana) were the most abundant neotropical migrants in all four phases of summer surveys, and both exhibited the most marked decline in post-impoundment surveys.
, grasshopper sparrows and a host of other songbirds are becoming less common, as well.
