A Tanager and Chat sang during the morning. Woodpeckers very active and giving unusual high pitched calls as they flew high from tree to tree. Very warm. May 21. Crew of workmen came up R.P. track with derrick to remove tracks and begin removing bridge. Hot in middle of day. Chickadees in family group. Saw a female Black- throated Gray Warbler on ground near back door. It made no sound but hopped along the ground advancing slowly toward the shaded spot under the group of redwoods. It flew into the redwood but I could not follow it as I had no glasses on. Later a gnome on the ground sang a very sweet finch-like whisper song as it hopped along on the ground. A female Lutecent Warbler came frequently into the Spineless bush near the electric pole, took worm, fled to room.
