TL;DR: This paper assessed the acquisition of three commonly used simultaneous discriminations; color, pattern, and form, using Coturnix quail as Ss, and found that form was the most difficult to discriminate, followed by pattern, then color, and little relationship between error trials or total trials to the criterion required for acquisition.
Abstract: Although a number of recent studies (Bartlett & Liebermann, 1960; Farris, 1964; Reese & Reese, 1962; Thompson, Loomis, & Loomis, 1965) suggest that Japanese quail make excellent Ss for the behavioral laboratory, there are no parametric data on instrumental discrimination learning with this species. This study assessed the acquisition of three commonly used simultaneous discriminations; color, pattern, and form, using Coturnix quail as Ss. The results showed, (a) form to be the most difficult to discriminate, followed by pattern, then color, and (b) little relationship between error trials, or total trials to the criterion required for acquisition, on the three stimulus dimensions.

TL;DR: The lipoprotein and apoprotein profiles of hyperlipidemic atherosclerosis-prone (HAP) Japanese quail showed resemblances to those of the CA quail, but expression of the 470 kDa protein in the lipoproteins appeared to be pronounced in HAP quail.
Abstract: The purpose of this study was to characterize the lipoprotein and apoprotein profiles of hyperlipidemic atherosclerosis-prone (HAP) Japanese quail. HAP and commercially available (CA) Japanese quail were fed either a semi-purified diet containing 1% cholesterol or a cholesterol-free diet for two weeks. The lipoproteins of CA and HAP quail fed cholesterol-free diet were composed of two fractions: densities ranging from 1.02 to 1.09 and from 1.09 to 1.21. The lipoprotein distribution patterns obtained from both strains showed an HDL-predominant pattern. A protein of 26 kDa was the major apoprotein in the entire density range of the lipoprotein class. Marked increases in the cholesterol ester levels were observed in the lower density fractions (1.006 < d < 1.055: chylomicron and VLDL fractions) of the cholesterol-fed quail, accounting for 46% of the total lipids in CA quail and 54% in HAP quail. In addition, the presence of a protein of 470 kDa was exclusively observed in the lower density fractions (1.006 < d < 1.055) of the cholesterol-fed HAP quail. The fatty-acid compositions of the chylomicron and VLDL fractions were affected by the dietary cholesterol in both strains: a decrease in concentration of 16: 0 and increase in 18: 0 (weight %). However, cholesterol feeding had no effect on the level of cholesterol, chemical composition or fatty-acid composition of the HDL fractions in either strain. Although the lipoprotein and apoprotein profiles of HAP quail showed resemblances to those of the CA quail, expression of the 470 kDa protein in the lipoproteins (d < 1.055) appeared to be pronounced in HAP quail. The relevance of these lipoprotein and apoprotein profiles to the genesis of atherosclerosis was discussed in this study.

TL;DR: There is a basal quantity of cholesterol deposited in the egg on which fiber intake, energy consumed, or egg production have very little effect and there is an inverse relationship between serum and tissue cholesterol levels and the total quantity ofolesterol excreted via the egg.
