Found in much of Central America, White-throated Magpie-Jay flocks are family groups led by a dominant female. They include a mate and several female offspring that bring food to the primary female and her young. It’s an example of cooperative breeding, when birds other than the parents help out to raise young.Support comes from Wild Delight Bird Food, offering a variety of blends designed to mimic the natural resources wild birds crave, available at Chewy.com.¡Escuche este episodio en BirdNote en Español!More info and transcript at BirdNote.org.Want more BirdNote?

Over 130,000 years ago, White-throated Rails migrated across hundreds of miles from Madagascar to the tiny island of Aldabra. Fossil records show that these wayward birds evolved to be entirely flightless, and went extinct when the island was lost to sea level rise. But some 20,000 years later, Aldabra reemerged from the Indian Ocean and a new wave of rails settled in. Today, the Aldabra subspecies of White-throated Rails are flightless once again! It’s a rare example of a phenomenon called iterative evolution.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

Do you ever see flocks of birds in your yard that show up in droves one year, but are completely absent the next? Some nomadic species such as Pine Siskins move based on the availability of food and habitat. It’s called irruptive migration, and it sometimes leads to backyards full of siskins. While these flocks are a delight for bird watchers, the dense groups can easily transmit diseases such as salmonellosis.This episode is brought to you by Wild Delight Bird Food, which aims to support wild bird populations with clean, nutritious ingredients in every blend.

Most bird species in North America mate for a single breeding season. Some may team up again the following year, just because both stay in - or return to - the same territory. Fewer than one-fifth of Song Sparrow pairs are reunited. Hawks, eagles, and ravens have wide territories, thus few contacts with the opposite sex. Maintaining a relationship through the winter may assure breeding in the next season.More info and transcript at BirdNote.org.Want more BirdNote? Subscribe to our weekly newsletter.

Some birds woo a mate by building the best nest. Males of many weaverbird species construct a series of intricately woven nests to impress a prospective partner. A male Red-winged Blackbird can even attract multiple mates if he controls prime breeding territory. Adélie Penguins construct their nests on mounds of stones, and partners often exchange stone gifts during the course of construction.More info and transcript at BirdNote.org.Want more BirdNote?
