Residues ofp,p′ dicofol,p,p′ dichlorobenzophenone (p,p′ DCBP),p,p′ dichlorobenzhydrol (p,p′ DCBH), 1,1-bis (4-chlorophenyl)-2,2-dichloroethanol (p,p′ DCD) and 1,1-bis (4-chlorophenyl)-2,2 dichloroethylene (p,p′ DDE) are reported in liver, fat, brain and oviducts of American kestrels exposed top,p′ dicofol. Breeding female kestrels were exposed to oral gavage dosages of 3.0 and 0.3 mg dicofol/kg body weight per day, equivalent to 1 or 10 mg dicofol/kg diet, for 39 days. Kestrels exhibited an eggshell thinning response similar to that produced by DDE, under these exposures. The major hepatic metabolite of dicofol in kestrels was DCD, but most organochlorine stored in tissues was in the form of dicofol. DDE was not a major metabolite of dicofol in kestrels. Compared with doves, kestrels had a significantly reduced metabolic capacity to transform dicofol to DCBP and DCBH, and had a steeper dose-response curve for dicofol-induced eggshell thinning.

Past work has suggested that successive reversal learning might be a valuable methodology for the calibration of inter-species performance differences. However, recent work has revealed that such learning is importantly influenced by variation in drive ( D) and incentive ( K) levels. To determine whether previously reported inter-species differences might have been the result of failure to equate D and K across species the reversal performances of Ringneck doves and pigeons on a spatial task were compared under two levels of D and one level of K.

The performances of Chukars, Ringneck doves and Greater Hill mynas on successive discrimination reversals were studied under conditions of correction and non-correction. Correction procedures significantly elevated the error scores of the doves and mynas, but did not affect Chukar scores.

SummaryStarch gel electrophoresis of the plasma of pigeons, ring neck doves, dwarf turtle doves, and mourning doves reveals constant distinct bands in the plasma albumin different for each species. In hybrids among some of these species, the albumin shows both parental components as double bands. The hybrids from dwarf turtle doves X ring neck doves are fertile. There were 24 progeny from one family in the first backcross plus 335 offispring from 58 second and later back-crosses and matings inter se of the back-cross hybrids. The ratios conformed to expectations on the assumption of a monohy-brid, co-dominant, autosomal gene pair. No linkage of the albumin types with the other characters was noted. A blurring of the non-albumin components of the plasma was noted in certain adult females of 4 species, a probable association with egg production.

Twenty-two progeny in a single backcross family of a species hybrid between the dwarf turtle dove and the ring-neck dove exhibited strong association in a repulsion phase of linkage between the silky feather trait and the species-specific hu-8 blood character. This family constituted a test cross for six characters: sex, peanut reactivity, silky feathering, and the three independent species-specific blood characters, hu-1, hu-4, and hu-8.
