Birds — Their Practical Benefit 

 to Horticulture 



Continued from page 6. 

 saw marlins foeil their young 312 in- 

 sects in l(i hours. Mr. Mosher made a 

 reeord of a pair of yellow throat warb- 

 lers eating plant lice in a birch tree at 

 a rate of (18 n minute for 41) minutes. 

 At this rate this one pair of birds would 

 destroy 7.3,000 of these insects in a 

 week. 



Harvey found .lOO mosipiitoes in the 

 stomach of a nighthawk and 00 grass- 

 hoppers in that of another bird of the 

 same .species. A scarlet tanager ate 35 

 gypsy moth caterpillars a minute for 

 18 minutes; a warbler ate 90 plant lice 

 in a minute, and a pair fed at this rate 

 for 40 minutes. .\ red-winged black- 

 bird had 28 cutworms in its crop. Fifty- 

 one species of birds are known to eat 

 hairy caterpillars, and 38 species feed 

 on plant lice. It is estimated that dur- 

 ing the stay of the birds in New York 

 state each season they destroy more 

 than 3,000,000 bushels of injurious in- 

 sects. Think of the consecpiences if the 

 birds were all exterminated. 



Is it worth while to try to save our 

 forests, our shade trees, our fruit trees'? 

 If so, we must stop the killing of insect- 

 eating birds. The gypsy moth, the 

 brown-tail moth, the leopard moth, the 

 elm tree beetle, and the tent caterpillar 

 have killed millions of trees in the past 

 few years, and today they are imperil- 

 ing every tree on the continent! 



The only way to check the increase 

 of these insects is to stop the killing of 

 insect-eating birds, and then let the 

 birds increase to their normal numbers. 

 Careful scientists tell us that if all in- 

 sect-eating birds were destroyed, the 

 whole continent would within three 

 years become absolutely uninhabitable 

 by reason of the myriads of insects that 

 would spring up and devour every liv- 

 ing thing. We are face to face with 

 this possibility. 



Ninety per cent of the normal bird 

 life of this country has already been 

 destroyed, and the other 10 per cent 

 will go in the next five years unless 

 drastic measures are employed to stop 

 the slaughter. The farmers and fruit 

 growers of this country are losing over 

 .$1,000,000,000 a year by reason of the 

 ravages of insects. Here are a few items 

 in this appalling expense account. 



The cf)tton growers of Texas are los- 

 ing .* 10,000,000 to .$50,000,000 a year by 

 reason of the ravages of the boll 

 weevil; and all because the quail and 

 the prairie chicken, the natural ene- 

 mies of that bug, have been practically 

 exterminated in that great state. The 

 cotton boll weevil is moving like a great 

 army to the eastward and to the north- 

 ward, and scientists sent down there to 

 study the situation tell us it will go to 

 the Atlantic ocean before it stops, and 

 as far north as cotton is grown, unless 

 the killing of birds is prohibited. The 

 wheat growers of the I'nited Stales are 

 losing over $100,000,000 a year by rea- 

 son of the ravage of the chinch bug. 

 Why'.' Because the (piail, the natural 

 enemy of that bug, has been almost ex- 

 terminated. The farmers of the middle
