The effect of embryonic development on the thickness of the eggshells of the coturnix quail The effect of embryonic development on the thickness of the eggshells of the coturnix quail
The average thickness of the shells from 75 unincubated coturnix quail eggs was found to be 0.193 mm. This was 7.3 percent greater than the average thickness (0.179 mm.) of the shells from 60 fully incubated eggs from the same hens. The two sets of eggs were collected simultaneously. This thickness difference was statistically significant (t-test:p< 0.005).

Biological data on PCBs in animals other than man Biological data on PCBs in animals other than man
SUMMARY: Polychlorinated biphenyls have become ubiquitous in the world ecosystem in quantities similar to those of DDE. Experimental studies have shown that PCBs have a toxicity to mallards, pheasants, bobwhite quail, coturnix quail, red-winged blackbirds, starlings, cowbirds, and grackles that is of the same order as the toxicity of DDE to these species. Overt signs of poisoning also...

A new species of warbler (Parulidae) from Puerto Rico A new species of warbler (Parulidae) from Puerto Rico
The West Indies are among the best known of the world's tropical regions, and our knowledge of the distribution of indigenous land birds in the Greater Antilles has been thought to be nearly complete (Bond, 1956). The last new species from the Antilles were described in 1927, the results of work in the Zapata Swamp of Cuba (Barbour and Peters, 1927) and the isolated Morne de la Selle in...

DDE at low dietary levels kills captive American kestrels DDE at low dietary levels kills captive American kestrels
Two of 14 male American kestrels died after 14 and 16 months on a diet containing 2.8 p.p.m., wet weight, p, p'-DDE. The brains of the two birds contained DDE residues of 213 and 301 p.p.m. compared with 14.9 p.p.m. (range, 4.47-26.6 p.p.m.) (wet weights) for 11 of the adult males which were sacrificed after 12 to 16 months on dosage. Autopsies of the two birds compared with autopsies of...
