Western Burrowing Owls (Athene cunicularia hypugaea) and Pulex irritans, the so-called human flea, have a curious host-parasite relationship. Although we’ve known about it for some time, many details of their connection remain unclear, including why it appears mainly in the northwestern portion of the Burrowing Owl’s range despite the fact that both species have much broader geographic distributions.
The Martial Eagle is one of the largest and most powerful of the booted eagles. These menacing giants dominate the skies over sub-Saharan Africa, ranging from Senegal to Somalia and down to South Africa.
Humans moving animals around for conservation?! This may not immediately sound like an action we should advocate for, but the purposeful movement of individuals from one place to another is often an effective way to give small, declining populations a boost in size or increase their genetic diversity.

Throughout western North America, the combination of longer, hotter dry seasons and dense forests is yielding more frequent, larger, and more severe wildfires, including immense “megafires.” Habitat loss from increased fire activity could put wildlife species that depend on mature forest at risk.
In the world’s temperate regions, proximity to roads usually reduces the reproductive success of birds, thanks to predators that gravitate toward habitat edges. However, the factors affecting bird nest success are much less studied in the tropics—so does this pattern hold true? New research published in The Condor: Ornithological Applications shows that interactions between roads, nesting birds, …
The two seabird species unique to Hawaii, Newell’s Shearwaters and Hawaiian Petrels, are the focus of major conservation efforts—at risk from habitat degradation, invasive predators, and other threats, their populations plummeted 94% and 78% respectively between 1993 and 2013. However, a new study in The Condor: Ornithological Applications offers hope of previously undetected colonies of these birds …
Twenty years ago when I was writing The Red Canary—the story of how in the 1920s a bird enthusiast and a biology teacher created a red canary—I needed to include an overview of the history of canary domestication. To obtain the necessary information, I started to collect eighteenth- and nineteenth-century books on canary breeding. As …
