This will enable us to disentangle the mechanistic relationships between exposure to urban stressors, oxidative stress, DNA methylation and telomere dynamics during development and the consequences for growth and survival in an altricial bird
Food and water interrelations and the protein requirement for growth of an altricial bird
, the cockatiel (Nymphicus hollandicus).
Among many altricial bird
species, the young within a brood do not hatch simultaneously, but over a period of one or a few days (Clark and Wilson 1981, Magrath 1990, Stoleson and Beissinger 1995).
Newly-fledged young of altricial birds
are normally not fully developed at the time of fledging and are dependent on parental food deliveries as they learn to fly, forage for themselves, and to detect and evade predators.
Nest predation as a selective factor in the evolution of developmental rates in altricial birds
Trees with dense vegetation cover would assure a good shelter for altricial birds
The young of altricial birds
, not only when they are in the nest, but as long as a month after leaving it, are fed by the parents....
The critical period for birds of this sort, the so-called altricial birds
that spend some time in the nest, is to get them just before they are ready to leave the nest.
Nesting success in altricial birds
. Auk 74:305-321.
In all altricial birds
, hatchlings come out with poorly formed pelvic bones that are still composed largely of cartilage.
The order Galliformes is characterized by precocial offspring, with breeding systems that reduce parental investment comparing with altricial birds
(Royle et al., 2012).
In nestlings of altricial birds
, the mouth gape is usually brightly colored, and different marking patterns, which disappear when the bird is weaned, may be present, depending on the species.
