Falco columbarius. 1889, September 14. Lake Umbagog. At Peaslee's Brook saw three small Falcons which I took to be Pigeon Hawks, playing together, alighting on the tops of the tall trees. There were several Blue Jays and one Canada Jay with them all frolicking together apparently on the most friendly terms. I landed and pursued them but could not overtake them. 1890, Lake Umbagog. October 7. Chases a Snipe. Outlet of Lake. We found eight Snipe of which I shot three and M. two. One bird that escaped us rose high and was flying in a great cir- cle after the usual fashion of Snipe when a Pigeon Hawk appeared and pursued it for a minute or more. It easily overtook but seemed unable to catch it although the Snipe did not double more than they usually do. Several times the Hawk closed in on it and for an instant the two birds seemed merged into one. Once the Hawk shot directly under the Snipe and turning sharply upward seemed to attempt to strike it from beneath, but failed in this also. Finally the Snipe pitched down into the grass and the little Falcon kept on and gave up the chase. 97
