Tenth annual report of the State ornithologist, E. H. BVmSDSB ( IffT. of 

 Mass., /:</:. pt. 1, pp. 75-101, pit. 5).— Under the beading of field work of the 

 year 1917 a brief report is given on the status of the heath hen, food of night 

 herons, sea bird colonies, the starling, Including B new means of breaking up 

 its roosting places and its destruction of gipsy anil brown-tail moth caterpillars, 

 pheasants, and the destruction of birds by the elements in the spring of 1M17, 

 with a list of the species found dead. 



Parasitism of nestling birds by fly larvae, O. E. Plath (Condor, 21 (1919), 

 No. 1, pp. 30-38). — Studies made by the author in the vicinity of Berkeley, 

 Cal., have shown nestling birds of many species to be parasitized by the maggots 

 of ProtocaUiphora azures and that the larvae of this parasite are dependent 

 upon blood in order to mature. The observations indicate that the maggots 

 attach to the nestlings at night and suck their blood, and rest In the lower 

 parts of the nest during the day. 



The chalcldld parasite Nasoriia brcvicornis was reared from the pups of P. 

 azurea, from 15 to 25 being obtained from each pupa. Small grubs from 

 infested birds' nests, which fed upon the pupa? of P. azurca, eating shell and 

 all, when reared to maturity were found to represent several species of moths, 

 including Tinea OC&dentella, Tinea sp., an oecophorid, probably Endrnsis 

 lacteeUa, etc. 



In investigations conducted by the author during a period of 11 weeks. 63 

 nests representing six species of birds were examined of which 39 were in- 

 fested by bloodsucking fly larva?. The author's observations of the effect of 

 this parasitism on birds are said to warrant the conclusions that from 5 to 10 

 per cent of the parasitized nestlings die from loss of blood; that some of the 

 parasitized nestlings which do become full-fledged are so weakened by the loss 

 of blood that they fall an easy prey to rapacious animals ; and that the larvae 

 of P. clui/sorrhua are probably more deadly to nestling birds than those of P. 

 a: urea. The latter conclusion is said to be borne out by a case of parasitism 

 recorded by Henshaw, 1 in which the mortality averaged about 90 per cent 

 instead of only 5 to 10 per cent. Accounts of parasitism of birds by P. azurea 

 by Content (E. S. K., 34, p. 359) and by Arnold (E. S. R., 40, p. 351) and by 

 ]'. chrvsorrhaea by Miller (B. s. K.. 21, p. 356), have been previously noted.

 of British Myriapoda.
