Mar 31 Aransas River, 5 1/2 mi ENE Skidmore, Bee Co., Texas in some elm? trees there, among them 2 Tmice identified by sight, not voice. They foraged there for a few minutes during which time I could not keep both of them in sight. One was blackish-crested, the other I didn't see. The former led the way to some blackbrush to the N, then again to growth across the stream as I approached. I followed up but couldn't locate the birds. Their only calls were soft pet pet. This is the area occupied by one of my "unmated males". I left at 4:40. Apr 1 Clouds came in during early morning hours and the sky was completely overcast at daybreak, remaining so until noon. The breeze came up from the S after 8:00 but not so strongly as on preceding days. The day was fairly warm, 68F at 6:30 am. I left the house at 6:30, walking to the creek S of the barn. No Tmice calls from that area so I walked upstream on the S bank, reaching the pipeline at 7:00. From there I walked S along the E fence of the Driscoll property. At a brown metal gate, the apparent entrance to the Rodriguez property I heard Tmice song peta peta to the east of the fence. I turned W toward the live oaks along the road leading S from the bridge. Crossing this road I proceeded NW in an area with dead brush scattered about, thoroughly "chained." At 7:20 I heard song peta peta north of me; I located the singer in the last liveoaks before reaching the riverbank woodland. There were two Tmice present and I stalked them patiently. The ♂ changed his song
