The month of April inspires poets, sometimes with contradictory results. Poet TS Eliot describes April as "the cruelest month." Shakespeare strikes an upbeat note, writing, "April hath put a spirit of youth in everything." Let April speak for itself. Listen to the birds.

A Red-tailed Hawk soars on broad, rounded wings, the epitome of effortless flight. Without flapping, it traces a leisurely, rising circle. The hawk is riding a thermal, a column of warm rising air generated near the earth's surface by heat from the sun. The Red-tail periodically circles to stay within the thermal. Riding thermals is an energy-efficient way to search for prey below.

A Burrowing Owl is about as big as a can of beans on stilts. Between the long legs, bright yellow eyes, and signature bobbing salute, these little birds are comical members of the western ecosystem. Cowboys riding Western rangelands have a nickname for these little owls. They call them “howdy birds” for the way they bob up and down in front of their nests.

The Santa Marta Sabrewing is a hummingbird species so rare, they’ve only been documented twice in recent years. Native to the mountains of Colombia, they were officially described in 1946. No one reported another sighting until 2010. They became a “lost” species, eluding every attempt to find them. Then in 2022, Yurgen Vega was studying the birds of a mountain range called the Sierra Nevada de Santa Marta. He snapped a photo of an unusual, large hummingbird – and the sabrewing was lost no more.

In the daytime, hot air rises as the sun heats the ground. The rising column of air is called a thermal, and it’s the perfect way for a Turkey Vulture to hitch a ride. Like an elevator to the skies, the thermal gently wafts the vultures upward. They move in a slowly ascending spiral around the thermal, rarely flapping and instead coasting on the breeze. When many vultures ride the same thermal, it’s called a kettle.

You might think the first bird species that humans raised in captivity would be a relatively small one, like a chicken. But evidence suggests that people in New Guinea reared the cassowary, often called the world’s deadliest bird, as much as 18,000 years ago, long before the domestication of chickens. The remains of cassowary eggs and bones at archaeological sites in New Guinea indicate that people gathered the eggs, possibly allowing the more mature eggs to hatch into chicks.

Great-tailed Grackles live up to their name. The glossy black males trail their long, V-shaped tails behind them as they fly, almost like a plane towing a banner ad. And while not quite as flashy, the brown-feathered females have impressively long tails, too. Also known as the Mexican Grackle, this species lives in all sorts of habitats from the northern coasts of South America to the western U.S. Their ability to live in both cities and farmland has helped Great-tailed Grackles expand as far north as Iowa.
