We document the first breeding record of Limpkin, Aramus guarauna (Linnaeus, 1766) (Gruiformes, Aramidae), for Louisiana, describe an additional unpublished breeding record from Georgia, as well as a possible record from Alabama, and associate these

Hurricanes Irma and Maria ravaged the mangroves of St. John, U.S. Virgin Islands, in 2017. Basal area losses were large (63–100%) and storm losses of carbon associated with aboveground biomass amounted to 11.9–43.5 Mg C/ha. Carbon biomass of dead

This paper contributes to the growing body of literature on the reproductive biology of South American birds by providing 823 records of reproduction for 197 species breeding within the Tumbesian biome of Peru and Ecuador. Where applicable, we includ

We observed Sanderlings (Calidris alba) with facial growths in coastal Louisiana, US during summer of 2016. Severe lesions were associated with lethargy and lack of a flight response. We determined that the skin growth etiology was a bacterium of the

Insectivorous birds may adjust their foraging strategies to exploit changes in resource distributions. Arthropod prey strongly influence habitat-specific persistence of long-distance migrant passerines in their wintering areas, and arthropods are str

Understanding the consequences of hurricanes on the food resources available to neotropical-nearctic migrant songbirds may provide important insight into the effects of hurricanes on migratory populations. During autumn migration 2006 we investigated

Grallaria and Grallaricula antpittas are poorly known ground antbirds (Formicariidae), which reach their center of diversity in the tropical Andes region. Here we review published literature on the reproductive ecology of these two genera, summarizin

Foraging behavior often reflects food availability, a resource that may increasingly limit breeding birds as intraspecific crowding increases. Measuring foraging behavior, therefore, provides a way to investigate effects of population density on food

Trade-offs in the allocation of finite resources among different stages of a breeding attempt as well as between different reproductive events should shape the evolution of life-history traits. To investigate the effects of incubation effort on withi

Dusky Flycatchers (Empidonax oberholseri) nesting in a mixed conifer-aspen woodland in southern Utah occurred at a breeding density of 0.44 territories/ha. Females began laying first clutches 1–26 June; adults fed nestlings (in renesting attempts)
