Structure and composition of the courtship phenotype in the bird of paradise Parotia lawesii (Aves: Paradisaeidae) Abstract Ethology is rooted in the idea that behavior is composed of discrete units and sub-units that can be compared among taxa in a phylogenetic framework.

Structure and composition of the courtship phenotype in the bird of paradise Parotia lawesii (Aves: Paradisaeidae)

This means that behavior, like morphology and genes, is inherently modular. Yet, the concept of modularity is not well integrated into how we envision the behavioral components of phenotype. Understanding ethological modularity, and its implications for animal phenotype organization and evolution, requires that we construct interpretive schemes that permit us to examine it. Extremely niche but...birdwatching iceberg : IcebergCharts. Youtube. Untitled. Evolution "failure mode": chickens - LessWrong. This post uses several directions in the recent (about 100 years) evolution of domesticated chickens (mostly, broiler chickens) to be a chilling illustration of the scenario "The Mindless Outsourcers" in The Future of Human Evolution (Nick Bostrom, 2004).

Evolution "failure mode": chickens - LessWrong

According to Nick Bostrom, there are two possible ways for future evolution of humans to result in a bad end for humans, because what end up being evolutionarily fit is not "nice". Two possible bad outcomes: Scenario I: The Mindless Outsourcers.

A Pocket Guide to Pigeon Watching - Workman Publishing

So Rosemary Mosco, a bird-lover, science communicator, writer, and cartoonist (and co-author of The Atlas Obscura Explorer’s Guide for the World’s Most Adventurous Kid) is here to give the pigeon's image a makeover, and to help every town- and city-dweller get closer to nature by discovering the joys of birding through pigeon-watching.

Posiblemente, si estos pájaros no se reuniesen en inmensas bandadas en determinadas épocas del año, nadie pensaría mal de ellos. Pero, por desgracia, es difícil deshacerse de una mala reputación, incluso cuando ésta es inmerecida. Y ese es el caso de los Estorninos. Bird Flight. Chukar Partridge flapping & climbing Source: Biplane wing planform and flight performance of a feathered dinosaur (Chatterjee and Templin 2007) -- Microraptor gui, a four-winged dromaeosaur from the Early Cretaceous of China, provides strong evidence for an arboreal-gliding origin of avian flight.

I was joined by a seagull chick. It was presumably hoping to score a piece of my sub. So why share this wholly unremarkable footage with you? Domestic Mallard from Palermo, CABA, Argentina on May 25, 2014 by Diego Carús · iNaturalist. These sparrows are singing a new song, in a rapid, unprecedented shift. Most birds have distinct calls that tend to stay the same.

These sparrows are singing a new song, in a rapid, unprecedented shift

It’s how birders can recognize a species without seeing it. But new research shows these tunes can change. Audubon’s Mystery Birds : UnresolvedMysteries. Washington's Sea Eagle - Audobon's Largest Unknown Bird : nonmurdermysteries. Compared With Hummingbirds, People Are Rather Colorblind. Birds are known for their visual prowess. Eagles are famously capable of seeing objects at a distance in vivid detail—they have roughly 20/5 vision compared to standard-issue human 20/20. But birds’ ocular superiority doesn’t stop there.

Galapagos finches caught in act of becoming new species. A population of finches on the Galapagos has been discovered in the process of becoming a new species. This is the first example of speciation that scientists have been able to observe directly in the field. Researchers followed the entire population of finches on a tiny Galapagos island called Daphne Major, for many years, and so they were able to watch the speciation in progress. The research was published in the journal Science. The group of finch species to which the Big Bird population belongs are collectively known as Darwin's finches and helped Charles Darwin to uncover the process of evolution by natural selection. Veery thrush song slowed down by New Scientist. New Caledonian crows can create compound tools: The birds are able to combine individual parts to form a long-distance reaching aid.

An international team of scientists from the Max Planck Institute for Ornithology in Seewiesen, Germany, and the University of Oxford have revealed that New Caledonian crows are able to create tools by combining two or more otherwise non-functional elements, an ability so far observed only in humans and great apes. The new study shows that these birds can create long-reaching tools out of short combinable parts -- an astonishing mental feat. Proper Names for a Flock of Birds. On a good day in the field, a birder might see a raft, a band, a host, a chime, and even a kettle. But what exactly are they seeing? What would you call a flock of flamingos, a swarm of swallows, or a group of eagles?

Different birds have different collective nouns to describe large groups, and while many of the terms are obsolete, seldom used, or just plain silly, they are still familiar to birders. Many flock names are descriptive not only of the group of birds but also of their behavior or personalities. Birders who understand these esoteric words and can apply them to the appropriate birds will enjoy birding even more.​ TYWKIWDBI ("Tai-Wiki-Widbee"): Frogmouth (with baby) Avian Hybrids – An Overview of Hybridization in Birds.
