DEVELOPMENT OF A YOUNG KESTEEL. 801 and tail lengthening considerably, especially the former ; this can be well seen by noticing the comparative lengths of the wings and tail shown in Fig. 2 (thirty-three days old) and Fig. 3 (forty-seven days old). In the latter two or three small tufts of down are still adhering to the feathers of the crown. With regard to the gradual acquisition of the full powers of the adult Kestrel I made the following FIG. 3. KESTREL. FORTY-SEVEN DAYS OLD. The meat upon which the chicks were at first fed was held in the beak while the tongue was thrust out beneath it, and then quickly withdrawn, so that the tongue-spurs, catching in front of the meat, dragged it into the mouth. It may be noted that the coloration of the tongue was very interesting, being salmon-pink with black spurs, and a transverse black bar between them and the tip. As soon as the chick could stand up, at the age of sixteen days, the muscles of the legs must have developed.
