Mr. lioardnian has several times taken llnMr ei,'i,'s from the clill's ol' Orand 

 Menan, where they lirced in Ai)ril, or early in May. In one instance he 

 found tiie nest in dose proximity to that of a jiair of Jtavens, the two 

 families Ijeiiij,' apparently on terms of amity or mutual tolerance. 



For several years two or more i)airs of these hints havi! heen known to 

 hrced rej^ularly on Mount Tom, near Xorthamjiton. Tho nests were jilaced 

 on the edges of ]ireci]iitous rocks very early in the .spring, the young having 

 been fully grown by the last of -hini'. Their young and their eggs have 

 been taken year after year, yet at the hiSt accounts they still continued to 

 nest in that locality. Dr. W. Wood has also found this species breeiling on 

 Taleott Mountain, near Hartford. Four young were found, nearly tltfdged, 

 June 1. In one instiince four eggs were taken from a nest on Mount Tom, by 

 Mr. V. W. IJennett, as early as April lii. This was in 1H(>4. Several times 

 since he has taken their eggs from the same eyrie, though the Hawks have 

 at times deserted it and sought other retreats. In one year a pair was twice 

 robbed, and, as is supposed, made a third nest, and had untledged young as 

 late as August. Mr. Allen states that these Hawks repair to Mount Tom 

 very early in the s])ring, and carefully watch and defend their eyrie, mani- 

 festing even more alarm at this early period, when it is ai)i)n)ached, than 

 they evince later, when it contains eggs or young. Mr. Jiennett speaks of 

 the nest as a mere apology for one. 



This Hawk formerly nested on a high cliff near the house of Professor 

 S. S. Haldenian, Columbia, I'enn., who several times jmicured ycmng birds 

 which had fallen from the nest. The birds remained about this cliff ten or 

 eleven months of the year, only disajipearing during the coldest weather, 

 and returning with the tirst favorable change. They la-ed early in spring, 

 the young leaving the nest jierhajjs in May. I'rofessor Haldenuin wjis of the 

 opinion that but a single jiair remained, the young disajipearing in the 

 course of the season. 



Sir John I>ichardson, in his Arctic expedition in 184ri, while descending 

 the Mackenzie Kiver, latitude i\'°, noticed what he ju'esumed to be a nest of 

 this species, placed on the clill' of a sanilstone rock. This Falcon was rare 

 on that river. 



Mr. MacFarlane found this sjiecies not uncommon on the banks of Lock- 

 hart and Anderson llivers, in the Arctic .egions. In one instance he men- 

 tions finding a nest on a cliff thirty feet from the ground. There were four 

 eggs lying on a ledge of the shale of which the cliff was composed, liotli
