From Thomas Mayo Brewer to Augustus Addison Gould1 [March 1858]2
My Dear Dr
In regard to the subject matter of Mr Darwins note to you I have to say that I have never known an instance in which 〈our〉 Yellow-billed Cuckoo has been known to drop an egg in the nest of any othe〈r〉 bird.3 I have however seen anest (—it was exhibited so not found in the field—) of the Chipping Sparrow containing the egg of a Black-billed Cuckoo—but I have always supposed it was deposited there by human 〈 〉
〈I know〉 of few birds more faithful apparently to their own young than both species of our cuckoos.
Very truly yrs | T M Brewer Dr A. A. Gould
