We describe a method for measuring gut passage time and seed dispersal distance for a large terrestrial frugivore. We attached temperature data loggers to radio transmitters in baits that were ingested by free-ranging cassowaries. The resulting [...]

We lured White Ibises (Eudocimus albus) to trap sites with decoy plastic flamingos and captured them with a rocket net or mist nets. Our ability to attract ibises to a site (and consequently our capture success) was affected by vegetation height[...]

High rates of Common Loon (Gavia immer) chick mortality have been documented in Wisconsin, especially on acidic lakes, but causes and timing of chick mortality are poorly understood. We modified and evaluated a subcutaneous transmitter implant t[...]

From March 1999 to August 2000, we used mist-netting, point counts, and radio-tracking to study habitat use, area requirements, and breeding of the Ivory-billed Woodcreeper Xiphorhynchus flavigaster in the tropical deciduous and semi-deciduous f[...]

We determined the distribution and relative abundance of resident and Nearctic-breeding, long-distance migrant grassland bird species in Cordoba province, Argentina. We sampled montane and lowland sites to determine if altitudinal differences mi[...]

We evaluated nasal discs and colored leg bands for Harlequin Ducks (Histrionicus histrionicus) wintering in the Strait of Georgia, British Columbia, by comparing marker visibility and life span, and determining effects of nasal discs on behavior[...]

Male and female Stripe-backed Wrens (Campylorhynchus nuchalis) have repertoires of learned, stereotyped calls that are specific to same-sex relatives in cooperatively breeding family groups. Consequently, they are potential cues for recognizing [...]

We investigated the effects of varying census duration on line transect estimates of winter bird abundance and species richness in second-growth coastal western hemlock forest fragments in Vancouver, British Columbia. Three treatments of census [...]

Avian field studies commonly employ colored leg bands to follow individual birds without recapturing them. However, this technique is subject to several types of reporting errors. In a laboratory setting under ideal conditions, we marked model b[...]

The nesting habitat of the Clapper Rail (Rallus longirostris) is not well studied in the southeastern United States. We documented Clapper Rail nest characteristics and surrounding habitats near Brunswick on the Georgia coast. Of 159 nests found[...]

The Galapagos Rail (Laterallus spilonotus) is endemic to the Galapagos Archipelago and little is known of its current status or population trends. In 2000, we surveyed 280 points in the largest population, on Santa Cruz Island, using call broadc[...]

Feather growth bar widths have become a standard index of nutritional condition in ornithological research. Traditional techniques of measuring these bars are difficult and slow because the bars are often hard to see. We present a fast and repea[...]
