On Tuesday I gave a lecture in my UW class about tool use and the cultural transmission of information in non-human animals. It's one of my favorite lectures; it does my heart good to ponder so many interesting examples of our connections with other animals. The list of discoveries of animals using tools is ever growing; ever since Jane Goodall discovered chimps using modified twigs to catch termites, researchers have observed crows in Australia manufacturing hooked tools to pry insects out of bark, dolphins carefully placing sponges over their rostrums to protect their tissues while foraging, chimpanzees using two tools (hammer and anvil) to crack nuts... the list goes on and on. Here's a truly great video of New Caledonian Crows figuring out how to combine a penchant for nuts and Read More
Paw Injury Makes Typing Difficult!
Apologies... I sliced the tip of my finger with a newly sharpened knife and it makes typing ridiculously slow and tedious. As a result I am terribly behind in most everything I have to do on a computer, which more often than not, is most everything I have to do for much of the day. At least it's not a dog's paw--I had a dog who badly cut his a pad on his paw and it was absurd trying to keep it clean and dry! In lieu of words, here are 2 photos a fantastic photographer, Nic Berard, took of Will (the same photographer who did the photos on the top of the blog and website), Lassie and me. I love the one of Will playing because he looks half insane (and who doesn't when they are completely lost in exuberance?) and I love that Lassie is in the background looking engaged and youthful (she was Read More
Lambs Thriving, Dogs Playing Is Warming My Heart
Much warmer now, might even be up to 20 degrees. Wow, feels like an entirely different place. The lambs are doing beautifully. On Sunday Jim and I opened up the panel dividing the two ewes with lambs and let them all in together. We wanted to wait to be sure that the lambs were well bonded to their moms (and vice versa) and that they were stable and healthy enough to tolerate being shoved around a bit by the ewe that wasn't their mom. Given how vigorous Snickers was (I am being so kind here, using the word vigorous instead of several others I can think of) when she was trying to reject her own little ewe lamb, I didn't want to subject the single lamb to that kind of abuse. However, we don't call him White Dude for nothing. He looks like he's in training for a starring role in professional Read More
Too cold; Feed the birds
It was 26 below this morning on the thermometer by the kitchen window, 36 below at a neighbor's. I suspect the temperature in the barn, which is down the hill from the house, was somewhere in between. Good grief. I was born in Arizona, and the concept that it is MUCH warmer in the freezer compartment of my refrigerator than it is outside just doesn't compute. It seems so very, very wrong. Lassie couldn't handle it at all. I took her out this morning, hoping she could urinate or defecate in seconds, but she stood outside for a few seconds and than ran inside and pooped on the dining room floor. She looked up at me while she did so as if she was concerned about what she was doing.... Am I being problematically anthropomorphic for thinking she felt unease about going in the house? (She has Read More
Jealousy versus Fairness in Dogs Part 2, Amazing Dog Video
Your comments have been so interesting about the 'fair' and/or "jealous" issue that I thought I'd respond in another post for everyone to read. I've included some of your comments, because they add so richly to the discussion. First off, I agree with many who've commented that we need to be very cautious about making interpretations from the results of this study. The bottom line is that while the dog's responsiveness degraded, as expected, if the food reinforcement was taken away, it degraded faster if another dog was observed receiving reinforcement. That was the "inequality aversion" that the authors mentioned (and yes, I believe it was the media that added "fairness" and "jealousy." The dogs also could receive one of two rewards, brown bread or sausage. While a similar primate study Read More
