The incidence of extra-pair paternity (EPP) is highly variable across bird taxa. While EPP is known to affect reproductive variance, the causes of temporal variation in rates of EPP are poorly studied. Breeding density has often been proposed as an i

We examined the effects of fire and canopy disturbance on turkeybeard (Xerophyllum asphodeloides [L.] Nutt.), a rare temperate forest herb. We used long-term data and a fire and canopy alteration experiment with controls to address our hypothesis tha

Little is known about the post-fledging period in most bird species, and almost nothing has been reported for the family Emberizidae, including New World sparrows. We report here, for the first time, the sizes (wing length and body weight) of, and th

Spiza americana (Dickcissel) colonized a restored Conservation Reserve Program grassland in Maryland during the second year of restoration and has continued to return in subsequent years. In 2000-2010, we banded 125 adult and hatch-year birds; during

Filter strips are strips of herbaceous vegetation planted along agricultural field margins adjacent to streams or wetlands and are designed to intercept sediment, nutrients, and agrichemicals. Roughly 16,000 ha of filter strips have been established

We studied the breeding biology of Grasshopper Sparrows (Ammodramus savannarum) on restored grasslands in Maryland from 1999 to present. We report the first documented cases of social polygyny in this species. Polygyny increased reproductive success

Adult male grasshopper sparrows sing two structurally and functionally distinct songs: buzz song and warble song. To investigate how these songs develop, we tutored three groups of young males in the laboratory: one with recordings, one with live adu

Currently over 14.6 million ha of land at an annual cost of US$1.76 billion are enrolled in the Conservation Reserve Program (CRP). The habitat benefits of CRP frequently are lauded, but documentation that wildlife is responding as hoped is urgently

While grassland restorations have gained recent popularity throughout the United States, few restorations have been initiated on the highly weathered soils of the Mid-Atlantic Coastal Plain; thus potential soil response to grassland management practi

The realms of rare species conservation and metapopulation biology theory are often interrelated, and hence share several basic challenges. Two of the most important are the critical and frequently difficult tasks of distinguishing a priori between h
