The ecological co‐dependency between plants and hummingbirds is a classic example of a
mutualistic interaction: hummingbirds rely on floral nectar to fuel their rapid metabolisms …

Were dinosaurs ectotherms or fast-metabolizing endotherms whose activities were
unconstrained by temperature? To date, some of the strongest evidence for endothermy …

Causes of interspecific variation in growth rates within and among geographic regions
remain poorly understood. Passerine birds represent an intriguing case because differing …

The study of avian nesting biology in North America and Europe has a long history, resulting
in an expansive and information‐rich literature. In contrast, the tropics have been relatively …

Embryonic development rates are reflected by the length of incubation period in birds, and
these vary substantially among species within and among geographical regions. The …

We document reproductive life history traits of the Three-striped Warbler (Basileuterus
tristriatus) from 146 nests in Venezuela and compare our results to data from the literature …

The swallow-tailed hummingbird Eupetomena macroura is a synanthropic species currently
in range expansion through southern Brazil. Although common, little is known about its …

Recent studies have described a new tropical lowland forest type in the Guianas, the tropical
lowland cloud forest. It is characterized by an enriched epiphytic species diversity …

Cooperative breeding in birds has traditionally been studied via long-term investigations of
single populations. In the last two decades the phylogenetic comparative method has been …

Endozoochory is usually involved in seed dispersal mutualisms, whereas ectozoochory is
non‐rewarding, and therefore neutral (or even negative) for the animal vector. Synzoochory …
