 twigs and shreds of soft bark, lined with horsehair and fine rootlets.

Crossbills, like other little pensioners of the trees, go and come 

 whenever the branches spread hospitable feasts. If the trees yield 

 no nuts, do not look for the jays or acorn-eating woodpeckers ; if it 

 is not a cone year do not expect the crossbills. But when the time 

 is ripe, some red letter day from high up in the treetops you may 

 catch the kimp, kimp, kimp, of a busy flock, and on some still luckier 

 day, like a whirl of snowflakes down will come a parti-colored band 

 with their queer crossed bills and coats of red or greenish yellow. 

 Then, if seeds and cones favor, perchance the flock will take up its 

 abode in the neighborhood and act as if it had always been there, till 

 suddenly some day it has disappeared and is seen no more. 



At Fort Sherman, Idaho, Dr. Merrill has seen crossbills in every 

 month of the year, though their occurrence was irregular. At times 

 they were as common and fearless as English sparrows, and on warm 

 bright days in February and March he says ' their pleasing song was 

 heard in every direction.' 



When Dr. Mearns was in Arizona he chanced on a good year and 

 found them among the commonest birds, drinking and bathing at 

 the springs and water places at all times of day.
