Maclura 1968 (4) (18 May) thrown in. If so - a full series of 4-6 of these is given, then pause and flap, then baird-note. i.e. - I heard display without je-jew, but never without the baird-note. the white-rump-like je-jew is also used in ground display. At one point I heard the note coming from the ground behind a small rise ca. 40 m. away. When I topped the rise I saw one bird making a short flight (ca. 5 feet) toward another bird on the ground. When they saw me they flew so I did not actually see the ground display. the focus of activity that I saw involved at least 2-3 displaying simultaneously plus 1 additional bird that did not display (I saw the 3 in the air together at one time). There were probably more, but I was most concerned with documenting the display. In the one case that I clearly saw a bird land it did not hold wing(s) in air after landing. In the afternoon I climbed the hill NE of Mastodon Fork. Found none there so I continued on to ridge to the east. Found a bird displaying off of the east of the broad saddle in the ridge. Saw it land in the rocky So. part of the spool, ca. 1/4 mi.
