Increasing populations of Hooded Mergansers (Lophodytes cucullatus) (Heusmann et. al 2000) may be out-competing Wood Ducks (Aix sponsa) for nest boxes on some sites in Massachusetts. Hooded Mergansers' use increased from ≤2% of boxes in 1979 to [...]

The Torrent Duck (Merganetta armata) is one of the four species of ducks that live in fast flowing rivers, and the only one inhabiting mountain rivers from Venezuela to Argentina. This study examines physical-chemical and biological environmenta[...]

From 2010?2012, I studied nesting success and causes of nest failure at a colony of Barn Swallows (Hirundo rustica) where anecdotal evidence suggested the colony was declining in size. In 2010, many nests were destroyed, and indirect evidence su[...]
Article
Warming temperatures have been linked to advancing spring migration dates of birds, although most studies have been conducted at individual sites. Problems may arise ecologically if birds arrive or depart before or after associated food resource[...]

Red-winged Blackbirds (Agelaius phoeniceus) experience high rates of nest predation and are therefore expected to exhibit adaptations to reduce the risk of eavesdropping by predators. We used a simulated predator and observations of adult and ne[...]
Article
Breeding populations of Mallards (Anas platyrhychos) have declined 38% in the northeastern United States over the past 17 years. One reason for this may be the reduction of a unique wintering habitat, artificial feeding sites. I hypothesize that[...]

We describe a new predator-prey relationship between Herring Gulls (Larus argentatus) and Chimney Swifts (Chaetura pelagica) at a communal roost in Sault Ste. Marie, ON, Canada. In a season-long study in 2015, we document 38 instances of predati[...]

In most dietary studies of fruit-eating birds, sampling methods consist of direct observations of foraging and fecal sample analyses, and the consumption of resource types is measured as the percent of occurrence in diet samples, or as counts (f[...]

Nest usurpation is a behavior where one individual takes over the active nest of another individual of the same or a different species. The Grayish Baywing (Agelaioides badius) has been reported as an occasional inter-specific nest usurper. In p[...]

High arctic latitudes are characterized by short summers with continuous daylight, high seasonality, and low temperatures. In stable bird populations, mortality risks associated with the harsh climate and/or the long migration to reach the Arcti[...]

Avian malaria is a common disease in songbirds, caused by protozoa in the genera Plasmodium, Haemoproteus, and Leucocytozoon. These parasites can negatively impact bird health, survival, and reproductive success. Four species of songbirds were s[...]

The Dark-eyed Junco (Junco hyemalis) is one of the most abundant birds in North America and exhibits versatility in its selection of nest sites. Although typically ground-nesting birds, juncos also nest occasionally in trees, on buildings, and i[...]

We studied the response of Water Rails (Rallus aquaticus) to conspecific and heterospecific playback to reveal any variation in reaction to playbacks of rail and crake and if and how these reactions change in intensity. Ten observation points, 1[...]

Coprophagy by breeding birds, whereby parents eat the feces of their nestlings, is a common but rarely studied behavior. By eating feces, breeding parents may recycle nutrients. In many passerines, eating feces also reduces breeders' time away f[...]

The behaviors of animals can be highly variable across individuals and environments; however, recent studies have demonstrated that the behaviors of individuals in response to similar environmental stimuli are often highly consistent over time. [...]

Western Chat-Tanagers (Calyptophilus tertius) are a rare and globally vulnerable songbird endemic to the island of Hispaniola. We conducted a radio-telemetry study of non-breeding Western Chat-Tanagers at two adjacent cloud forest sites in Sierr[...]

The use of tracking devices (tags) to investigate seabird movements and habitat use has grown rapidly over the last 30 years, but often tracking data are reported without assessment of the effects of tags. The extra mass and bulk may risk alteri[...]

Caribbean Martins (Progne dominicensis) are common breeders on most Caribbean islands, where they regularly roost and nest in urban areas from February through August. However, from September through January, the basic ecology of this species?it[...]

Grebes are unique among birds in ingesting their own feathers. This behavior and the subsequent ejection of feathers as pellets have long puzzled ornithologists, who have tended to treat feather-eating and pellet-casting as independent behaviors[...]

Whereas most host species parasitized by Brown-headed Cowbirds (Molothrus ater) accept cowbird eggs in their nests, others reject the foreign eggs or desert parasitized clutches. Chipping Sparrows (Spizella passerina) are a nest deserting host o[...]
