A bird of paradise with incredibly black feathers, the better to display its electric blue feathers.
Watch the video of its courting dance!

I have just spotted this light mystery book free today on Kindle. Theme is wild bird smuggling in the Sea of Cortez.

Amazing that they are so clustered in a certain land area.

Here is a study showing us how birds see, as they have a fourth cone cell which registers UV.

Bird species are in decline.

Industrial agriculture land use is largely responsible.

Uni of Sheffield states the bloomin' obvious in a new study of birds.
The species have chicks which mature at a rate which depends on environment and habits. A migratory bird has to be ready to migrate. A songbird hoping to have three clutches in a good season, has to have chicks which can be independent juveniles after weeks, not months.
They say nobody has put this into a science report before and they'll keep looking into it.

Cassowaries are flightless so their feathers can look more like a mop of hair. A new study looked at fossil feathers and learned the mechanism for the glossiness of their feathers. This is not the same as the glossiness of a flighted species.

Another study, which must have been fun, looked at hummingbirds and their vision. They can see the ultraviolet unlike us.

"Each morning, the researchers rose before dawn and set up two feeders: one containing sugar water and the other plain water. Beside each feeder, they placed an LED tube. The tube beside the sugar water emitted one color, while the one next to the plain water emitted a different color. The researchers periodically swapped the positions of the rewarding and unrewarding tubes, so the birds could not simply use location to pinpoint a sweet treat. They also performed control experiments to ensure that the tiny birds were not using smell or another inadvertent cue to find the reward. Over the course of several hours, wild hummingbirds learned to visit the rewarding color. Using this setup, the researchers recorded over 6,000 feeder visits in a series of 19 experiments.

The experiments revealed that hummingbirds can see a variety of nonspectral colors, including purple, ultraviolet+green, ultraviolet+red and ultraviolet+yellow. "

Stunning landscape photos. Here's the article and winner.


Above is the website and amazing entries.
By valuing the landscape we value the natural flora and fauna of the landscape.

Hákon Gunnarsson | 37 comments Very good photos. All worthy of being there, but I like the one in fourth place most. There is something so simple, and abstract about it. Still, they are all very well done.
