What reading level is Birds in Their Relations to Man a Manual of Economic Ornithology for the United book?
To quickly assess the difficulty of the text, read a short excerpt:
Of one hundred and fifty-five stomachs of cuckoos taken between May and October, inclu- sive, by the Biological Survey, only one contained berries. Nearly half of the food consisted of different kinds of cater- pillars, mainly hairy ones.
During May and June, when tent caterpillars (Clisiocampa americana) are stripping orchards of everything green and leaving on the bare branches their unsightly nests, they form 13 YELLOW-BILLED CUCKOO. (After Biological Survey. ) 194 BIRDS IN THEIR RELATIONS T...O MAN.
nearly half of the cuckoos' fare. These birds are unique in having a taste for insects that other birds reject. Most birds are ready to devour a smooth caterpillar that comes in their way, but they leave the hairy varieties severely alone. The cuckoos, however, make a specialty of devouring such unpal- atable creatures : even stink-bugs and the poisonous spiny larvae of the lo moth are freely taken. About six per cent, of the food for the year consists of beetles, among which are a few potato-beetles.
