Editorial. 
A Cowbird'S Nursery : in " Bird Lore " (July— August, 
1909) is an interesting paper from the pen of C. G. Abbot, which 
is of such interest regarding a parasitical species that I am quoting 
it almost in extenso ; it also introdiices to us another species 
which is practically unknown to English aviculture, viz., the 
Chestnut-sided Warbler {Dendroica pensylvanica) : — 
"Where ignorance is bliss, 'tis folly to be wise — and, to judge by the 
"serenity of her expression, the little Chestnut-sided Warbler in our 
" picturet has not the least suspicion that the three eggs which she is 
" brooding so happily are not all of her own laying. Who knows but that 
" it may even be to her a source of pride that two of them are considerably 
"larger than the third, giving jn-omise as they do of babies twice as lusty 
" as those of her neighljours ! " 
"Asa matter of fact it is the lazy Cowbird. When the rightful 
"owner of the nest has been absent, no less than two eggs of this shiftless 
" vagrant have been imposed upon her for incubiition and care. Whether 
" both were laid by the same bird I could not of course determine, but the 
" fact that the eggs were quite differently marked would indicate perhaps 
" that two Cowbirds had visited the nest." 
" As a general thing, I have no hesitation in destroying every Cow- 
" bird's egg I find. For although the Cowbird in itself is a harmless bird, 
" its advent into the world seems to be attended by the sacrifice of other
