Amazonian bird chicks mimic poisonous caterpillar to avoid detection

A trio of researchers has found and documented the case of a newly hatched bird with plumage that mimics a poisonous caterpillar to ward off predators. In their paper published in American Naturalist, Gustavo Londoño, Duván García and Manuel Sánchez Martínez, describe finding the young birds and observing their habits while in their nests.
 
 

Here's How Birds Make Do Without External Ears

Birds have the incredible ability to hear different sounds even though they don't have outer ears like mammals do.

In fact, birds can perceive whether the source of a sound is above them, below them, or at the same level. But how do they do it?


Lateral eyed birds like blackbirds, ducks or crows can discern the height of lateral sounds very precisely to the sound volumes. Frontal eyed birds like the barn owl have specific hearing capacities for frontal sounds.

Basic Canary Care

Keep your pet canary out of any drafts. A drafty room can kill a canary! Keep any heat vents, air conditioning, fans, etc. on the opposite side of the room from the canary cage. The best check is to hold a lit candle next to the cage. If the flame flickers it is probably too drafty. 

Common Health Problems Of Love Birds

 Who doesn’t love having birds around, especially in their homes? They make sweet chirping sounds, that make you visibly calmer even when you are not really calm. They make your home a better place to live in, don’t they? But, birds can become quite a responsibility too. 
 

Birds in Indonesia: 1,605 Confirmed, 126 Threatened

Based on Burung Indonesia's data, the number of bird species in Indonesia has increased from 1,598 in 2012 to 1,605 species in 2013. “There have been seven newly recorded species in the country in 2010-2012,” Jihad, Bird Conservation Officer of Burung Indonesia said. 

Do mating songs stir up birds’ emotions?



A bird listening to birdsong may experience some of the same emotions as a human hearing music, report researchers who worked with white-throated sparrows.

“We found that the same neural reward system is activated in female birds in the breeding state that are listening to male birdsong, and in people listening to music that they like,” says Sarah Earp, who led the research as an undergraduate at Emory University.

How young finches know which songs to mimic



Scientists have discovered the neurons that let juvenile songbirds recognize the vocal sounds they’re learning to imitate.

These neurons encode a memory of learned vocal sounds and form a crucial (and until now only theorized) part of the neural system that allows songbirds to hear, imitate, and learn its species’ songs—just as human infants acquire speech sounds.

The Essential Nutrient Your Pet Bird Could Be Lacking

Just as humans need sunshine and vitamin D to prevent disease and be optimally healthy, so do our avian friends.
Domesticated birds like psittacines (parrots) and passerines (finches, canaries and other perching birds), need natural direct sunlight for certain metabolic processes to occur, and for a number of other health reasons as well.

Identifying birds by their bird’s nests

Have you ever noticed a bird’s nest and wondered what type of bird built it? Hopefully, the following information will help you in making that identification.
A bird’s primary consideration when choosing a nesting site is security. Birds fall into two general nesting categories: cavity nesters and non-cavity nesters. A cavity nester is a bird that will build a nest in a hollowed tree, cactus or birdhouse (nesting box); somewhere they can be enclosed and protected. Obviously then, a non-cavity nester is a bird that will build a nest in a tree, in a bush, or on the ground; in a place where they are in the open.
