Parus Apr. 25. Spring Creek, 6 1/2 mi. ENE Skidmore, Bee Co., Texas I walked N, reaching windmill nest at 8:20. I circled that area to N & back to creek at 8:45 - no calls. I climbed tree and looked down into vertically-opening cavity but could see nothing inside. Reddish brown fecal castings, possible of raccoon nested in notch a few inches from opening. After 9:00 am I walked N along W bank of tributary running N-S I detected no thrush calls in half an hour there. 9:37 - 9:45 - no calls nor song from along creek informing territory of the late #514. Showers intermittent. Apr. 27. Overcast; breeze from SE scarcely noticeable although there were strong gusts occasionally, I listened along the creek for 3 or 4 minutes after 8:00 but heard no song where #514 had his territory. I walked to the windmill nest at 8:25 climbed the tree and found that I could see no more details with a flashlight than without. I circled through the post- oaks near the windmill and worked both banks of the tributary from gully to S beyond deep gully to N of road. I remained in area until 9:15 and heard no thrushes. I am certain that if there had been a family party in the area, I would have located it under those conditions.
