A pair of Common Ravens harassed a Red-tailed Hawk on the southern edge of the Baselands this morning between 7:30 and 8:00. I heard one of the Ravens make that growling, croaking sound they give while it was flying across the open area to the south of the Wet Woods. It flew up to the top of a hydro pole where the other Raven sat, and they were bill touching until they noticed the hawk, when they both flew over to the tree where it was roosting. They didn't caw like crows but just sort of sat there glaring at the hawk until they got bored and flew off to the west. The two ravens looked to be about the same size as the hawk, if anything, slightly larger.
Not long after that, I saw a small flock of Bonaparte's Gulls flying overhead, going from east to west, and just after that a single Loon also flew over, but I didn't get a good enough look to say what type. Other interesting birds included four Horned Grebes, all singles, and all associating with Red-breasted Mergansers, although it was hard for any kind of waterfowl not to associate with the mergansers since they were everywhere. One of the Horned Grebes was noticeably paler than the others. Also three Red-necked Grebes, one single and a pair.
