Unha vez rematado o ensaio da pesca de mergullo, a xove gaivota transporta a sua pedra á beira, onde exercitará o pescozo soltando-a e recollendo-a repetidas veces, asà coma aprende a asociar formas, texturas, cheiros e sabores.
I've had the company of a generation or two , or three of these tiny jumping spiders that live in between my window and the bug screen. I bought a pair of laser pointers (red & green) that I've been messing around with for about a week, when I noticed one day that they reacted to the green laser pointer when I pointed it out of the window. One of them scurried over to the green spot with such haste! Some of them react aversively, others sometimes aggressively chase down the bright green spot. So I setup my Canon 60D to record a behavioral test session with my leading subject, Earl. Sourced From Wiki, I learned that "Jumping spiders have very good vision centered in their anterior median eyes (AME). These eyes are able to create a focused image on the retina, which has up to four layers of receptor cells in it (Harland & Jackson, 2000). Physiological experiments have shown that they may have up to four different kinds of receptor cells, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultraviolet range. It seems that all salticids, regardless of whether they have two, three, or four kinds of color receptors, are highly sensitive to UV light (Peaslee & Wilson, 1989). Some species (for example, Cosmophasis umbratica) are highly dimorphic in the UV spectrum, suggesting a role in sexual signaling (Lim & Li, 2005). Color discrimination has been demonstrated in behavioral experiments."
I bet you'll never forget this :) CAT Eye Photography | Facebook | 500PX | Twitter | About Me |
There are stereotypes for almost every race of people in the world. Our acceptance of these stereotypes is an antisocial behavior itself, but it can often lead to more dramatic antisocial behaviors such as violence and persecution. Photo from www.foreignpolicyblogs.com
The Behavioral Operations Management Summer Institute for PhD students at the Ross School of Business of the University of Michigan, Ann Arbor (BOMSI2019). The lead faculty were Ryan Buell (Harvard Business School), Stephen Leider (Ross School of Business, University of Michigan), and Jordan Tong (Wisconsin School of Business, University of Wisconsin-Madison). From the website, "The inaugural Behavioral Operations Management Summer Institute for PhD students will be held June 10-14, 2019, at the University of Michigan, Ross School of Business in partnership with the Center for Value Chain Innovation. The conference is co-sponsored by the business schools at the University of Michigan, and the University of Wisconsin-Madison. Support for this event is also being provided by Harvard Business School's Technology and Operations Management Unit. The 1-week intensive summer institute is designed to provide PhD students who are interested in behavioral research a solid foundation to conduct behavioral operations management research. Additionally, we hope that the summer institute will encourage collaboration and the creation of a research community among the next generation of researchers. Each day of the institute will include morning and afternoon sessions. Morning sessions will provide a general overview of BOM, review core behavioral economics/psychology topics, and discuss OM applications. Afternoon sessions will be focused more on small groups, practicums (e.g., applying ideas to actual research activity), and roundtables (more informal discussions). There will also be free time to prepare for the next day, have office hours, pair up to work on ideas, and hang out!" Pictures from the sessions taken over the week.
In various stages of moving toward alternate or breeding plumage. Surfbirds tend to use rocky shores most of the time locally, but I assume these were stopping on the sandy beach during migration northward. They were actively feeding.

I found this Northern Cardinal in a tree in our backyard. At first I thought it was dead, and a hawk or something had left it there. But then it hopped up and began to flit around the trees and started to sing. It looked perfectly fine.
I would really appreciate it if someone could tell me what was going on. It was about 95 degrees, so maybe it was something heat-related?
