Produktbeschreibung
Excerpt from Proceedings of the United States National Museum, 1879, Vol. 2 In the following paper are given the measurements of all the eggs of the eight species of Empidonax that are in the collections of the Smithsonian Institution, and also those in my own, and also a few others. Three of these species, E. minimus, obscurus, and hommondi, so far as is known, have eggs that are uniformly of an unspotted white. If ever spotted, they arc so very rarely and so very slightly as hardly to constitute really an exception. In another species, flaviventris, of which, so tar as I am aware, only five or six well-identified sets have been secured. at least two well-identified sets have been taken that are entirely of an unspotted white color, the others being all more or less spotted and marked. All the remaining four species, traillii, acadieus, pusillus, and difficilis, have eggs strongly marked, though, among them all, eggs are occasionally found that are of an unspotted white, or marked with very minute spottings. In the following brief mention I chiefly confine myself to the size of each egg, its locality, and the authority for its identification, if the record has been preserved. Empidonax hammondi, Baird. Four eggs in Museum of Comparative Zoology, Cambridge (No. 1681), from Blue River. Colo., Edwin Carter, measure .62 x .52 ; .60 x .54; .62 x .52; .64 x .53, averaging about .62 x .53 T. M. B.´s cabinet No. 1921. Anderson River. MacFarlane. .67x.52; .68 x .51., The first set is smaller and more rounded than average eggs of E. minimus, but they are otherwise indistinguishable.
