On my lunchtime walk today I saw both pine and palm warblers, and two whitethroated sparrows in excellent plumage. The pine was in a deciduous tree about 20 feet off the ground on what I consider the outbound part of the path (the side nearest the Charles) near where the path turns right to return, flitting around the way you expect warblers to. The palm was close to where the path along the ridge comes back to the main path, between waist level and about eight feet above the ground, wagging its tail and flitting around etc. It didn’t have a chestnut cap, so I’m really saying “palm” on the basis of the tail wagging.
The river has been pretty low lately, nowhere near as low as last August or September, but below the bottom of the broken bridge abutment or whatever that is.
