We studied the response of nesting grassland birds occupying short-grass and mixed-grass prairie sites 2 and 3 y following two, large-scale wildfires that burned ≥360,000 ha in the Texas Panhandle in March 2006. Nest success was greater on burned p

Natural resource managers are increasingly applying tree reduction treatments to piñon–juniper woodlands to meet a range of ecological, social, and economic goals. However, treatment effects on woodland-obligate bird species are not well understoo

Two general migration strategies prevail among temperate-breeding migratory songbirds of North America. Most “Eastern” birds migrate relatively directly from breeding to wintering grounds immediately after molting, whereas a substantial proportio

Oak savanna, once widespread across central North America, has functionally vanished from most of its range because of land conversion or fire suppression, but much oak savanna remains in the Cross Timbers ecoregion of the south-central United States

The lark sparrow (Chondestes grammacus) is a ground-nesting passerine that breeds across much of the central North American steppe and sand barrens. Through genotyping and sequencing of avian malaria parasites we examined levels of malaria prevalence

We examined abundance and diversity of arthropods in nests of lark sparrows (Chondestes grammacus). No true ectoparasite occurred in the nests sampled (n = 69) and no ectoparasite was found on nestlings. However, 67% of nests contained non-parasitic

Black-tailed prairie dogs (BTPD; Cynomys ludovicianus) have often been labeled as keystone species because of their ability to strongly influence grassland ecosystems. I used line-transect surveys and distance sampling to compare breeding bird and ma

Shrubs, such as mesquite (Prosopis spp.) and cholla (Opuntia spp.), now dominate fire- suppressed grasslands in southwestern North America. Responses of birds to prescribed burning of the shortgrass prairie in this region are poorly understood. We ex

Methods for monitoring bird nests might influence rates of nest predation, but the effects of various methods (e.g., visual markers and observer visitation rates) are often separately investigated among disparate avian taxa and geographic regions. Fe

Wildfire and conversion of sagebrush (Artemisia spp.) shrublands to cheatgrass (Bromus tectorum) grasslands is a serious threat to the shrubsteppe ecosystem, but few studies have documented wildfire's effects on birds with multiple years of pre-and p
