About

The Yellow-winged Blackbird is a conspicuous species of the Southern Cone of South America, congregating in colonies in marshes during the breeding season, and forming larger flocks in wetlands, grasslands, and agricultural fields the rest of the year. These birds are also extremely vocal, giving a startling variety of calls, including sharp and percussive sounds, clear and musical whistles, and a range of other rattling, chirping, whining, whirring, and gargling vocalizations. Their song in particular makes use of virtuosic trills, robotic whistles, and mechanical whirring or buzzing sounds, coming across as half bird, half sci-fi robot. This iconic song is also the source of one of the Yellow-winged Blackbird’s nicknames, “trile,” and some authors propose it may also be the origin of the name of the country Chile! As if to make the most of their raucous acoustic capacity, the males of an entire colony will sometimes sing together in one big, cacophonous chorus.

In addition to nesting together in the same space, Yellow-winged Blackbirds also synchronize their nesting in time. Most of the females in a colony will lay within several days of each other. As a result, most of the nests in the colony will be on the same timeline, with eggs and nestlings developing at about the same time across the marsh. (snip)



Historic Oregon Bill Generating Conservation Funding Is Signed Into Law

Oregon will soon have a new, dedicated source of conservation funding to support the recovery of struggling bird and wildlife species across the state. House Bill 4134, dubbed 1.25% for Wildlife Bill, passed the Oregon State Senate in February and has now been signed into law by Governor Tina Kotek. American Bird Conservancy (ABC) strongly supported the 1.25% for Wildlife Bill, a proactive measure expected to raise up to $30 million annually for wildlife conservation in the state.

“This is monumental: Oregon has chosen to invest in its wildlife and its future with the passage of this historic law. Habitat restoration, recovery programs, and anti-poaching efforts are just a few of the programs that will be funded by this landmark legislation,” said Hardy Kern, ABC’s Director of Government Relations.

The Act will create a sustainable funding source dedicated to conserving imperiled species like the Marbled Murrelet, a seabird that nests in mature and old-growth forests in the state. Nest predation by jays and ravens contributes to the species’ declining population. Actions that could boost nesting success, such as campground cleanup efforts to reduce jay and raven numbers near sensitive nesting sites, are currently unfunded, but could benefit from the revenue generated by the newly signed law.
