78 EXPERIMENT STATION RECORD [Vol. 92
Cross-mating of Canada geese with Emden geese, A. W. BLAIN (Auk, 61
(1944), No. 3, pp. 389-391, illus. 1).
Brood habits and growth of "blue grouse," L. WING, J. BEER, and W. TIDYMAN.
(Wash. State Col. et al.). (Auk, 61 (1944), No. 3, pp. 426-440, illus. 1).--On
Dendragapus fuliginosus and D. obscurus, "the West's premier game birds," which
inhabit mountain forests from Alaska to New Mexico. The principal work in this
study was concentrated in the general area accessible from Conconully, Okanogan
County, Wash., on the east side of the Cascades, summer of 1940.
'Preliminary notes on the development of nestling pileated woodpeckers,
J. S. Y. HOYT. (Cornell Univ.). (Auk, 61 (1944), No. 3, pp. 376-384, illus.
2).-The work here reported upon was done on Ceophloeus pileatus abieticola
nesting in the vicinity of Ithaca, N. Y.
Food crops for game birds on farm lands, A. M. PEARSON and D. G. STURKIE
(Alabama Sta. Cir. 90 (1944), pp. 20, illus. 28).-Much of the food needed by
game birds in Alabama can be provided by diversified farming; the principal need
for special wildlife plantings on farm lands is to alleviate the food shortage usually
most severe during March-April. Such plantings are compatible with good farm
management and for the most part should be located along field borders and fence
rows. Detailed information as to where, when, how, and what to plant is' presented.
Germination of seeds after ingestion by ring-necked pheasants, W. G. SWANK
(Jour. Wildlife Mangt., 8 (1944), No. 3, pp. 223-231, illus. 4).-In the investigation
reported, the percentage of seeds escaping digestion varied among different
species; those with hard seed coats were most frequently passed uninjured. Other
things being equal, smaller seeds were passed in greater numbers than large seeds.
Seeds that had passed through the digestive tract of the pheasant germinated more
quickly than those not so exposed. Soft-coated seeds (e. g., alfalfa, nightshade,
millet, flax) were almost all digested, but some passed uninjured and viable. Wild
grape, which has a very hard seed coat, showed the greatest resistance to breakage
in the digestive tract, but over 75 percent of its seeds were digested. A large proportion
of rose seeds were broken and digested; utilization was sometimes over
95 percent of those eaten. It is recommended that seeds for food plat mixtures
include some easily digested and others that are resistant. On management projects,
advantage may be taken of the capacity of pheasants to disseminate seeds of food
plants in the places they frequent, thus reducing the amount of artificial propagation
required to establish adequate food and cover.
Occurrence and distribution of the trematode Collyriclum faba (Bremser)
in birds, D. S. FARNER and B. B. MORGAN. (Univ. Wis.). (Auk, 61 (1944), No.
3, pp. 421-426).-This trematode parasite has been reported from 2 orders, 13
families, 24 genera, and 26 species of birds. The purpose of this paper is to record
a new host (cowbird), give a brief review of the literature (30 references), and
present a parasite-host list with its geographical distribution, believed to be complete.
Notes on the pupal development of Stilbometopa impressa (Diptera:
Hippoboscidae), C. M. HERMAN (Jour. Parasitol., 30 (1944), No. 2, pp. 112118).-This
common blood-sucking parasite of quail in California has been reported
only from Lophortyx spp.; the present study is based on material collected
entirely from L. californica vallicola and deals primarily with pupal development.
The flies leave their host to deposit their larvae but do not exist away from it more
than 5 days; deposition may occur at any time of day. The puparium passes
through a series of color stages until it becomes shining black, the process taking as
long as 16 hr. The adults emerge in 61-162 days, the time for the pupal stage increasing
as winter advances but not in any definite progression. Injury or contact
