We humans learn some of our earliest life lessons from our brothers and sisters, watching what toys our siblings play with and what treats they stash away for later. In this Halloween season podcast, Ari Daniel Shapiro journeys to Austria to learn how such social learning happens in a spooky bird—the raven. Image Credit:

American Crows (Corvus brachyrhynchos) abound in the US, although they stay only in the higher elevations in Arizona. These were recorded just North of Durango, Colorado, in October, 1997. Listen to the difference between the Northwestern Crow and the American Crow, which may or may not be the same species - my money is on two species.

Northwestern Crows (Corvus caurinus) like everyone to know where they are. If they are in the area you'll know it by this well-known "caw". In this case two Crows perform a duet for your listening pleasure. They are wonderful "talkers" and they have lots of variations on the "caw" theme. Listen for the differences in these two, which appeared to be a couple. Northwestern Crows are considered by many experts to be the same species as the American Crow (C. brachyrhynchos), which is somewhat larger, and has a different voice.

In late February I was fortunate to find a gathering of Ravens consisting of over 200 birds! The birds wheel and dive, roll, spin and generally show off, many holding twigs and sticks in their beaks while they fly. Their acrobatics took my breath away, and this recording is some of the wing sounds of one those wild flights.

Here is a sample of their calling en masse.
-
A hapless Raven (Corvus corax) sits in a Piñon Pine in Sedona, Arizona. He has been "pinned" here by a pair of Phainopeplas, which alternately sit a foot above his head, waiting for him to fly so they can harrass him again. The first three plaintive notes are him begging for mercy, and the final set of "caws" is when he gives up, flying away and making as much noise as possible ("Maybe", he thinks," if I'm really noisy, they'll leave me alone"...he was wrong!)

The call of 2 seconds consists of five individual notes. This is the last of a series of identical calls that were repeated every 10.5 seconds or so. This call is distinguishable from calls uttered in flight (similarly harsh, but single spaced notes), or those heard when they assemble at night perches (a frog-like croaking). The species is increasing in numbers in Gauteng province and beyond. Date: 20 October 2022. Source: Own work. Author:
