Citizen-science recordings prove to be a useful tool in detecting diel patterns in birdsong When listening to birds sing, we often wonder: what are they “saying”? To whom are they singing? For decades, researchers have extensively studied birdsong and the
Do you sing like I do? Geographic variation in the vocalizations of a Neotropical sparrow species complex Variation in phenotypic traits are common in geographic scenarios, and conspicuous when geographic isolation is involved. Genetic, morphological and cultural traits are all
Passive restoration contributes to bird conservation in Brazilian Pampa grasslands Passive restoration (natural colonization) has been tested and used as tool to recovery-degraded habitats, mainly in forests. Researchers have investigated for the first time that southern South America grasslands in
Microhabitat nest‐site selection by ducks in the boreal forest The boreal forest is one of the most important breeding areas for ducks in North America, but there is little information about the nest ecology of ducks from this region.
Researchers develop an effective tool for reducing mammalian predation at nests of critically endangered Florida Grasshopper Sparrows Predation is a common cause of nest failure for many birds, but sometimes predation rates can be high enough to warrant action
Gambling at a high-elevations: the risks of enlarged eggs for Mountain Bluebirds Most studies that have looked at why female birds lay the number of eggs they do, and no more, have focused on the consequences of having too many

Notes on the breeding biology of Rufous Potoos in lowland Ecuadorian Amazon Potoos are some of the most intriguing birds of the Neotropics. Strictly nocturnal and very hard to see, they hunt insects from a perch, with a technique similar
Foraging White Ibis target inter-habitat prey movements in the Florida Everglades In the 1800s John James Audubon wrote of the Florida Everglades, “We observed great flocks of wading birds flying overhead toward their evening roosts …. They appeared in such
