We examined the extent and causes of band-related leg injuries in an Australian passerine, the Bell Miner (Manorina melanophrys). Eight percent of banded birds exhibited leg injuries, and most were birds with two plastic color bands on a tarsus.[...]

Studies of the dynamics of carcass components are critical to understanding survival and reproduction in waterfowl. Here, we examined the influence of sex, age, and season on the carcass composition of American Wigeon (Anas americana) in the Sou[...]

Although ephemeral ponds act as small hotspots of plant, invertebrate, and salamander diversity, the importance of such ponds for birds has been little studied. We hypothesized that ephemeral ponds on the Cumberland Plateau in Tennessee would su[...]

Feathers are increasingly collected as a nondestructive source of DNA for avian genetic research. Although feather samples are not optimal in some important ways than more robust blood or tissue samples, feather sampling requires less training f[...]

Understanding variation in the detectability of birds is fundamental to determining the reliability of survey methods. We examined the influence of lunar light conditions on the detection probability of Whip-poor-wills through repeated sampling [...]

The Louisiana Waterthrush (waterthrush; Seiurus motacilla) is a forest-dwelling, Nearctic-Neotropical migratory passerine that nests along streams. We attached radiotransmitters (0.6-0.8 g) to 12 nestling waterthrushes using snug, elastic loops.[...]

We describe the deleterious effects of using an antimony potassium tartrate emetic to obtain diet samples from birds, and compare information obtained from regurgitated samples versus fecal samples in describing diets of autumn migrants. We also[...]

In 2003 and 2004, we placed 41 floating nest platforms on Grassy Lake in southeastern Wisconsin (USA) to test the hypothesis that reproductive success of Black Terns (Chlidonias niger) is limited by the quality of suitable nesting habitat. Extre[...]

Many birds undergo bare part color changes during the breeding season. Most investigators have focused on color as a signal of individual quality. An alternative, but not exclusive, function of bare part color may be signaling readiness to breed[...]

Territorial behavior of Broad-tailed (Selasphorous platycercus) and Rufous (Selasphorous rufus) hummingbirds in Colorado was measured at sites with feeders containing10%, 20%, and 30% sucrose solutions, respectively. The presence or absence of t[...]

Egg flotation was used to estimate incubation age and eggshell evidence was collected to determine nest fate at nests of 11 species of shorebirds on the Arctic Coastal Plain of Alaska during 2002-2004. We present egg-flotation schedules for nine[...]

Bands are a common marking method in bird studies and capture-mark-reencounter (CMR) models are often used to analyze banding data. Common to this family of models are two assumptions: marks do not fall off or become unreadable and individuals w[...]

In at least 15 species of woodpeckers, the inner primaries of nestlings are reduced in size. This trait is polymorphic in Acorn Woodpeckers (Melanerpes formicivorus) at Hastings Reservation in central coastal California, where most nestlings (90[...]

We evaluated the hypothesis that social group size in Mexican Jays (Aphelocoma ultramarina) varies with habitat structure. We counted the social group size of Mexican Jays over a range of elevations and forest types in a single mountain range in[...]

The distribution of marine birds relative to water clarity was examined in the nearshore waters of Monterey Bay, California. I conducted nine at-sea surveys in 1999 and 2000 and simultaneously recorded water clarity and the density of five taxa [...]

Data from roosts of Amazona parrots may be useful in creating demographic models, because these birds exhibit high roost fidelity and pairs are conspicuous in flight. However, few investigators have attempted to track changes in the number of pa[...]

Conservation-oriented studies of Micronesian Kingfishers (Todiramphus cinnamominus) have been hindered by a lack of basic natural history information, despite the status of the Guam subspecies (T. c. cinnamominus) as one of the most endangered s[...]

Counts of nest starts are often used as indicators of the size of avian nesting populations, or of avian productivity. However, the accuracy of single or repeated counts of unmarked nests over time for estimating seasonal numbers of nests may be[...]
