April 21, 1963 - Tree Swallows Tree Swallows Exclusive Sunday Review sketch by Dennis Puleston of Brookhaven Focus on Nature by Paul Stoutenburgh, Cutchogue Every once in a while I want to take a moment to thank the many kind and thoughtful people who take time out of their busy day to drop me a note concerning their thoughts and observations on nature. Surely these are most appreciated and reinforce my be- lief that many of you are in tune with much of the world about you. Thank you all. ps. Last week a group of us took it field trip that included tine Quogue Sanctuary. This delightful spot, through the years, has be- come one of our regular stops whenever we are in the area. There are walks around the ponds shat, with the aid of glasses, ran reveal untold secrets. Why we even saw wild turkeys there! And one of the Beau Bremnmells ac- Companied us completely around our tour. Besides the many trials there is also a good selection of wildlife such as raccoons, fox, skunks, hawks, and birds of all sorts that are kept in neat and healbhy confinement. But of all the things I saw there, I remember most vividly the many tree swallows about the ponds. As usual, they were tire- lessly darting and diving with that characteristic occasional stall or almost stop in mid air as they snatched an insect. The tree swal- lows have been here for some weeks now. They are always the earliest arrivals of the swallou4 clan. As a matter of fact, they also linger in the fall the lates. The reason being that they, unlike other swallows, have acquired the technique of sustaining themselv- es on vegetable matter such as bayberries, fruits of red cedar and Virginia creeper when in - sects become inactive due to cold weather. Judd Bennett, who has contributed to this column many times, has had them in his bay- berry when they literally cleaned every berry from sight. Many of the other swallows do not have this ability and therefore curing severe cold snaps thousands per - isih from starvation. Some of you may remember a few years back when our own early martins were caught in just such a disastrous predicament. These late migrants congregate by the thousands on many of the telephone wires in this area. This is particularly a familiar sight along the south shore and one can rest assured that when you see these great concentrations the tree swallows are getting ready for their winter vacation. They usually wind up as any winter vacationist does in the southern states or along thw Gulf. Ot course, there always has to be some who yen for foreign travel and venture to Mexico or Guatemala. Usually for most, however, where there is a plenti- Nil supply of insects — there will be their resort. If you have not seen this beau - tifol blue - green bird with its pure white underside, it's time you made his acquaintance. At the sanctuary in Quogue, we were able to walk within 10 feet of him as he perched on a limb outside his man - made box. Along all the trails, you will find boxes, each with its tenant, content with man's innovation for nature's best. Eons ago when man had not cleared the woods, the mar- tins and swallows had no problem in finding the many abandoned woodpecker holes for nests. To- day with the scarcity of trees and the additional problem of our European intruder, the starling, few nesting sites are left. Almost anyone can have these do - gooders (insect catchers) in their yard by putting up an appropriate box. The only requi- site is a box with a one and a half inch hole situated five to ten feet off the ground preferably facing the open field. Yo,ar only problem might be the English Sparrow who invariably finds these boxes during the winter before our southern guests arrive. Here your Yankee ingenuity, I am sure, will be able to discour- age Mr Sparrow. When you do have the swallow nesting, he will build his nest out of grass and trim it with feathers. This use of feathers is almost invariably used by this swallow. In the boxes along our wood's the feathers are usually from the neighbor's chickens. We, by the way, live near a salt marsh in which we have placed many box- es on stakes. Ponds, streams, and wetlands of all types are favorite haunts for the swallows because of the numberous insects about and so they provide the ideal spot for nesting sites. It's still not too late to have your boy or the handy man around the house build a few box- es for these worthwhile swallows. It is surprising how much good one of these birds will do in reaping a harvest of insects each day. This alone would make the bird worth attracting to your area bat the sheer joy of watching swallows with their never - ending flight is probably the greatest joy of all:
