Lawrence Peregrines: feeding time!

The three chicks started off the morning under fair skies, calm winds, and temp at 56F.  The forecast for the day ahead calls for partly sunny, with a high near 61. East wind 3 to 8 mph.  Had nice looks at morning feeding session just after 5:30 AM, and the three chicks were very hungry and eager to gobble up the offered prey from the female.  The fourth and final egg remains unhatched.  Hopefully it will hatch some later today!

2018.0516-001Most brooding of the small young is performed by the female, though the male occasionally takes short turns.  No attempt is made to share brooding simultaneously.  Apart from weaker motivation for brooding, a male still has greater difficulty in covering a full brood of chicks than a clutch of eggs. Although the actions of the brooding falcon are essentially similar to those of an incubating bird, there are slight and gradual adjustments appropriate to the change of covering delicate but growing nestlings.  Leaning forward and stepping around gradually cease, but shuffling movements become important, evidently to place the feet below the chicks.  Rocking stops on hatching, and other settling motions are replaced by gentle lowering of the body onto the nestlings.
