Janich 1953 8 Asio flammeus July 15 Point Barrow, Alaska after my last visit now has 2 dead chicks and 4 fertile eggs with advanced embryos. Next reported July 8 by Dill Maker abandoned, with one egg punctured and not piped as he reported. Six eggs were fertile with well-formed embryos and a 7th was extra large, malformed, and thin shelled. I saw no short-eared owls today. Wholesale abandonment of nests, just as the chicks are hatching or are about to hatch seems to me to be due to other factors than human interference, although this seems to be the final element in several cases. It may be that the abundance of jaguars and the unreasonable cold and overcast have turned this area into one which this owl is not equipped to meet. July 20 Deserted nest near S.E. corner of plot L.E. has 4 fertile eggs and one infertile egg. Deserted nest on Beach Ridge between two antennae has 5 eggs, 1 infertile egg, 1 embryo dead before the desertion, and 3 well developed embryos apparently alive at time of desertion. July 22 Nest about 250 yds S. of snowy owl nest #3 has four downy young and one infertile egg. Three weanling lemmings lay at the edge of the nest. Site on broad high polygon among tufts of course grass (Arctagrostis?) that is now growing.
