“…In fact, the number of diagnostic bands was very low in this family, and some bands taken as identical by descent could actually be different given that a further re‐examination revealed that some of them could not be exactly the same band in size, and their intensity on the Southern hybridization was different. The band patterns obtained with multilocus radioactive probes can be misleading and difficult to interpret in some cases, especially when the potential fathers are relatives, the population is highly inbred or when additional bands appear in the offspring due to mutation (see for instance Lubjuhn et al . 2002).…”

“…According to accessibility, 79 nests were closely monitored in one sector of the colony as part of an ongoing study of the breeding behaviour of the species (e.g. Lubjuhn et al 2002, Masello et al 2006a and references therein, Masello et al 2006b). Nests were inspected every five days by climbing the cliff face.…”

The bright colours of parrots are caused by psittacofulvin pigments, which appear unique to this Order, and by structural colours. We measured red (psittacofulvin), green (mixed) and blue (structural) colours of wild burrowing parrots Cyanoliseus patagonus of northeastern Patagonia, Argentina, and measured nestlings regularly to obtain data on breeding success and nestling growth. As adult feathers are moulted outside the breeding season, adult body condition could not be measured directly during feather growth, and climatic conditions were used as an indirect parameter. The colony of burrowing parrots is surrounded by Monte steppe habitat, the breeding success has been shown to depend strongly on the climatic patterns. The area experienced a drought with very poor breeding success as well as a year of above‐average precipitation during the study period, serving as a natural experiment. We thus analysed the variability of colouration within the population among and within breeding seasons. We observed strong inter‐annual differences in nestling and adult colouration. Nestlings grew blue feathers with lower achromatic brightness during better conditions, and when controlling for year effects, nestlings with higher mass and from more successful families also had blue feathers with lower achromatic brightness. Adult blue feathers showed the same trend, with lower achromatic brightness in the moult following breeding seasons of better conditions. In contrast, during better conditions, adults grew red feathers with higher achromatic brightness and the colour hue was also affected, and the hue of the red region of nestlings varied with the hatching order. The colour of all three regions of nestlings varied between nests, and the colour of the red region of adult males positively correlated with breeding success (clutch size, brood size). In summary, the present data suggest that environmental conditions contribute to variability in both structural and the psittacofulvin‐based colours of wild burrowing parrots.

“…Nestlings from each brood fledged also asynchronously, with an interval of 2–3 days between nestlings (Masello and Quillfeldt 2002). Burrowing parrots have a socially and genetically monogamous breeding system with intensive biparental care (Lubjuhn et al 2002, Masello et al 2002, Masello and Quillfeldt 2003). The nestlings remain in the nest for about 60 days (Masello and Quillfeldt 2002).…”

P. 2004. Are haematological parameters related to body condition, ornamentation and breeding success in wild burrowing parrots Cyanoliseus patagonus ? Á/ J. Avian Biol. 35: 445 Á/454.Haematology and plasma biochemistry values are useful tools for ecological research. They have been used to investigate the physiological state and the adaptation of individuals to their habitat, changes in nutritional state of birds, body condition, the level of parasite infestation, male quality, the physical condition of nestlings, etc. In the present study we tested the role of haematological and plasma biochemistry values in burrowing parrots Cyanoliseus patagonus (Aves, Psittaciformes) for determining individual quality and condition. We measured triglyceride levels, plasma protein levels, plasma hue and erythrocyte sedimentation rate of nestlings and breeding adults in a colony in the north of Patagonia, Argentina. We found that plasma triglyceride levels strongly relate to changes in individual condition. Plasma levels of triglycerides were found to be strongly related to mass change, hatching order and brood size in nestlings. Levels of triglycerides were found to reflect reproductive effort in adults: males fledging larger broods had decreased levels of triglycerides. Adults with lower body condition had increased erythrocyte sedimentation rates. Plasma hue showed a strong relationship with an ornamental trait, the red abdominal patch of male adults, and with parameters of structural body size. Thus, we have shown that haematological and plasma biochemistry values, especially plasma levels of triglycerides, are good indicators of individual quality and condition in nestlings and breeding birds.
