Observation details

Swimming in the river when I arrived to lead the PBC bird walk. Tossing its head as if it were uncomfortable. Flew low downriver, sadly before the participants arrived. Young bird. EDIT: changed to tundra EDIT: Starting to have my doubts about this ID. I called it a TRUS at the time because my recollection was that immature TRUS have black at the base and tip of the bill while TUSW have paler pink at the base. The other field mark I used was an apparent V at the top base of the bill, which is one of the classic field marks that guides claim distinguishes the species. Looking at photos since then, it looks like there is some variation in both of these characteristics within the species. Also, immature TUSW are more likely to be fairly light like this bird at this time of year. Still favoring TRUS is what looks like quite a flat head and straight top edge of the bill. I'll leave it as TRUS for now so it can be reviewed.
