Yep, crows have pretty good eyesight. Speaking of chipmunks, I used to have one shamelessly come to the window where I would put some peanuts out every day for jays and chickadees. This particular chipmunk just couldn't help himself and tapping on the window wouldn't stop him from stuffing his cheeks (he'd just look at me for a moment and then carry on with stuffing). I would have to literally open the window to get him to run off and save some for everyone else. However, as soon as I look away (my PC at home is next to the window), he'd be back stuffing his cheeks again. Perhaps it just couldn't see me that well, as you said, heh. Crows will craft and use tools in the wild[1]. Their intelligence always surprises me, though I think most of us are predisposed to assume birds are not that intelligent when compared to other animals. I used to think that myself before making the study of birds a hobby. Crows snip into the leaf edges and then tear out neat strips of vegetation with which they can probe insect-harboring crevices. These tools have been observed to come in three types: narrow strips, wide strips and multi-stepped strips—which are wide at one end and, via a manufacturing process that involves stepwise snips and tears, become narrow at the opposite end. Studies show that New Caledonian crows are capable of meta-tool use, at a level rivalling the best performances seen in primates. One such study involved putting food in a box out of the crows' reach. The crows were given a stick that was too short to reach the food. However, this short stick could be used to retrieve a longer stick from another box, which could then be used to retrieve the food. This complex behaviour involved the crow realising that a tool could be used on non-food objects, and suppressing the urge to go directly for the food. It was solved by six of seven birds on the first attempt. This behaviour had previously only been observed in primates.
