THE OOLOGIST

home, none the worse for their little 

 adventure. Then Mr. Parsons decend- 

 ed, and we set off in the two boats in 

 quest of the Heron Rookery. As we 

 drew away from the tree, the old 

 Eagles returned to their nest with a 

 couple of large fish, and when we last 

 saw them, the Eaglets were greedily 

 eating, and probably telling their par- 

 ents of their strange adventure. 



After we had worked our way 

 through the swamp for about a half 

 hour we began to hear the coarse 

 croakings of the Herons, and soon we 

 saw the great birds flying around their 

 nests in the tree tops. The nests 

 were mostly in Water Elms and there 

 were as many as five or six nests, 

 sometimes, in one tree. We did not 

 try to make any estimate of the num- 

 ber of birds nesting, but it is claimed 

 that about three hundred pairs nest 

 there annually. The nests all seemed 

 to contain young, so there was no use 

 trying to get any good eggs. After en- 

 joying the unusually interesting sights 

 offered by this Rookery, we started 

 for the lake. Arrived there, we board- 

 ed the launch and made our way to 

 the opposite shore, where we took the 

 trolley for the city, having spent a de- 

 lightful day in the open.

Broad-winged Hawk. 



May 31st, 1912, while R. C. Harlow 

 and myself were working along a steep 

 mountain side that faced the river we 

 heard a hawk note that was strange to 

 me. I just, got a glimpse of the bird 

 iteslf. 



Locking about we were unable to 

 see a nest. Nothing but a Porcupine 

 in sight, low down in a little hemlock, 

 so after getting the prickly fellow 

 down and having a little fun with him 

 we let him go and started on out the 

 mountain. We had gone but a little 

 distance when a Hawk, alighting close 



by and calling her note which was 

 new to me, but was at once recognized 

 by Mr. Harlow as a Broad-wing. 



Climbing up I found four nicely 

 marked eggs, pretty well covered with 

 fresh Birch leaves. According to Mr. 

 Harlow's experience in the Eastern 

 part of the state four eggs is a large 

 set. Two or three being the usual 

 number. 



I had never expected to find this 

 Hawk breeding here as in over twenty 

 years I have never seen or had but 

 positive records. One being of an 

 adult Broad-wing that was brought to 

 be mounted. The other record was of 

 one that I shot myself a few years ago.

Nesting of the Osprey at Pompton 



Lake, New Jersey, During the 



Spring of 1912. 



On the 13th and 14th of April of 

 that year a pair of Ospreys (Pandion 

 halieatus carolinensis) appeared on 

 Pompton Lake, Passaic Co., New 

 Jersey, and were seen diving and fish- 

 ing throughout both days over the en- 

 tire length of the lake. Later on May 

 2d, I was informed by several of the 

 natives that a pair of Fish-hawks had 

 commenced a nest on the west shor^ 

 cf the lake in a dead poplar. 



On May 15th I visited the site of 

 the nest and found the female incubat- 

 ing a clutch of three eggs apparently 

 completed only several days prior to 

 this visit. These eggs measured 2.->'J 

 xl.88; 2.44x1.80, and 2.36x192 and 

 were pale cream color heavily blotcit- 

 ed with brilliant chestnut brown es- 

 pecially at the large end where the 

 blotchings were intermingled with a 

 decidedly deeper shade of brown. The 

 nest was a bulky mass of sticks about 

 three feet across and one a half feet 

 deep and was placed on a horizontal 

 branch close by the trunk of the tree 

 about forty feet from the ground.
