IN COLOR 



Bird-Lore for January-Feb- 

 ruary (Vol. XII, No. i) con- 

 tains colored figures of the 

 Grasshopper,. Henslow's 

 Baird's and LeConie's Spar- 

 rows. 



The series was begun in 

 Bird- Lore for November- De;- 

 cember, where the Chipping, 

 Field, Tree, Clay-colored and 

 Brewer's Sparrow^s..:were fig- 

 ured. 



The demand for December, 1909, 

 Bird-Lore has so exceeded our esti- 

 mate that, in spite of the fact that 

 we printed an unusu&Hy large edi- 

 tion, the supply is now exhausted. 

 We will, however, send a copy of 

 the Sparrow plate (the first of the 

 Sparrows of North America in 

 color) which appeared in that num- 

 ber, to all subscribers to Bird-Lore 

 for 1910 (.Vol. XII), in order that 

 their series of these plates may be 

 complete. 



Single numbers 20 cents. 

 Annual subscription $1.00
