- Data collected as part of the Northern Bald Ibis reintroduction project confirms the idea that flying in v-shaped formations helps migratory birds save energy. (For more on this topic, see also Ed Yong's post linked below.)
- Using cameras strapped to falcons' heads, a scientist found that falcons intercept their prey using a strategy called constant bearing. Instead of flying directly towards their prey, they fly towards their prey's future position. This strategy has also been documented in bats and dragonflies.
- So far 70 Barred Owls have been shot to help Northern Spotted Owls recover their former territories.
- The extinction of the Passenger Pigeon may hold lessons for California Condor conservation.
- The new 15-year plan for condor conservation may expand public access to the Blue Ridge and Bitter Creek national wildlife refuges in California.
- Long-eared Owls are easy to miss because of their camouflage.
- In American West, Common Ravens often center their territories around power lines.
- While macaw parents usually lay four eggs, it is unusual for them to raise and fledge more than one chick. This seems to be a way of hedging their bets: laying extra eggs ensures that at least one hatches, and devoting extra attention to a single chick makes it more likely that at least one chick will survive.
- Two endangered Whooping Cranes were found shot in western Kentucky.
- A new study connects the behavioral differences in white-striped and tan-striped White-throated Sparrows to a specific gene.
- Male Spectacled Warblers use a wide and variable repertoire to build their territorial songs.

- Canada's conservative government has been systematically destroying scientific records and disbanding federal research institutions. While the main target has been institutions and archives that support climate research, the damage has gone well beyond that.
- The Pineland Commission rejected a plan to build a pipeline through the Pinelands. It was a rare win for the state's environmentalists.
- Somerset County has acquired an additional 350 acres for the Sourland Mountain Preserve.
- It looks like Norway will exterminate its wolf population.
- While it has not yet collapsed completely, the retreat of the Pine Island Glacier in Antarctica is now irreversible.
- The loss of big carnivores is a substantial ecological threat because of the effects they have on herbivores (and indirectly on plant populations).
- State and federal estimates of the danger posed by the recent chemical spill in West Virginia are based on almost no data. Here is more about the chemical involved in the spill.
- The EPA finally published its first regulation of carbon emissions from new power plants. Nebraska is already suing to block the new regulations.
- A planned Pebble Mine would pose a serious environmental risk for Alaska's Bristol Bay.
