I added more images of the same bird, taken shortly after this photograph. I hope they might help you make an ID. (The photographer says this is a Sharp-shinned Hawk, Accipiter striatus. Not sure if I can get him to respond by describing his reasons for this ID, but will try).

Life and Death of a Male Paraphidippus aurantius Jumping Spider

tags: , , , ,
After taking the video of an adult male Paraphidippus aurantius eating a cricket and waving his arms threateningly at the videographer's finger, both the male and an adult female P. aurantius were released on a nearby plant.
As stated in the video, the videographer did not intentionally cause the female to kill the male. The videographer says, "I was actually a little concerned that the female might try to get him, so I put them about three or four feet apart and went back inside for a little bit to put away the containers I was keeping them in. When I came back, the female had found her way over to the male. Without touching the plant or interfering with the scene in any way, I took a series of photos documenting her approach and eventual attack."

Nam et ipsa scientia potestas est (And thus knowledge itself is power)
-- Sir Francis Bacon.
Have you read an especially good essay about psychology, behavior or neurobiology lately? If so, why not share it with the world by submitting the URL for this essay to a blog carnival designed to share excellent writing with others? You don't need to be the author of an essay to submit it for consideration, and this is one way that blog carnivals grow in size and influence: by sharing with others.

Moochas Smoochas to all my DonorsChoose Donors!

Oct 28 2009 Published by under Education, Teaching

tags: , , , ,

Here's the latest news from DonorsChoose: collectively, all of the blog writers and the 4,038 citizen philanthropists who participated in the Social Media Challenge have raised more than $565,000 to help more than 99,000 students in public schools throughout the US!!! I think this is amazing! JUST the ScienceBloggers team has raised an astonishing $54,358 from 244 citizen philanthropists (my blog has raised $5,646.31 so far -- last year, the ScienceBlogs team raised $38,000 and my blog raised $2,884.55)
But there's still three days to go, and I want all of us to continue raising money to help impoverished classroom kids make progress towards realizing their dreams. We have three days left, let's do everything we can to give more funds for these worthy projects!

Arm Movements of Male and Female Tutelina Jumping Spiders

tags: , , , ,
Here is some video (and stabilized from some really shakey footage using Deshaker, a plugin for Virtualdub) of male and female jumping spiders from the genus Tutelina. Not sure on the species, but the videographer's best guess is Tutelina elegans. The female could be mimicking the antennae movements of an ant. The music was recorded by the videographer.
