Here you'll find field recordings of the snipe, the surprising walrus (who does not «coo coo ca choo»), the common virtuoso katydid, and hundreds of others as well, including, of course, the rather more familiar sound of the homing pigeon, a.k.a. rock dove and Columba
livia domestica.

The paper maps passenger pigeon genetic data to a published genome from the Rock dove, Columba
livia, and uses these data to infer changes in their population size through time.
David Dickman and Le - Qing Wu of Baylor College in Houston, Texas, collected seven homing pigeons (Columba
livia) and inserted electrodes into their brains to record the activity of individual neurons.
They captured 97 free - ranging pigeons (Columba
livia) in the highly urbanized suburbs of Paris and kept them in cages outdoors for 1 year, feeding them a diet of corn, wheat, and peas.
In the new study, published online today in Science, Dickman and BCM biologist Le - Qing Wu placed seven homing pigeons (Columba
livia) in a dark room in the center of a cube - shaped set of magnetic coils.
They then compared genetic sequences with the genome of the still common domestic pigeon (Columba
livia) and, based on those comparisons, estimate they captured between 57 and 75 percent of the passenger pigeon's genetics (assuming that its genome was roughly the same size as its relative's).
A brief stroll yields frequent sightings of Canis familiaris (the dog) and Columba
livia (pigeon), as well as occasional glimpses of Equus caballus (horse) and Rattus norvegicus (rat).
