Went for an evening walk in the Don Valley, heading north from the Riverdale Park bridge. Lots of great wildlife sightings, but no camera with us to record things. First we saw an adult beaver sitting on a rock and grooming itself all over. Then we came upon two sapsucker nests in trees perhaps 100 feet apart. The young were keeping up a constant din. We saw several Baltimore orioles and many yellow warblers. We then hit a section of the trail filled with cottontails, at least 3 or 4 popping in and out of view. Then we came across a creche of Canada goslings, watched over by 3 adults, one of whom had a neck collar on of some sort. We followed a raccoon heading upriver on a mission. Then we stood by a pond and watched American toads swim about and call. One actually came out of the water and approached us, we like to think because of our poor attempts to imitate the calls. We saw a couple more cottontails on the way back.
