Abstract: Knowledge about the embryonic stages of birds is important in answering many questions about development and evolution. We give the first description of 41 embryological stages of the monk parakeet (Myiopsitta monachus) on the basis of external morphology and comparison with the chicken. We also provide measurements of some external morphological characters (i.e. body mass, crown-rump, beak, forelimb, and third toe lengths) and perform comparisons with other precocial and altricial birds with the aim of identi… Show more

“…For example, they appear at day eight in zebra finches ( Taeniopygia guttata , Passeriformes) and pigeons (Columbiformes), at day ten in chickens ( Gallus gallus , Galliformes), Japanese quail ( Coturnix coturnix , Galliformes), and Peking ducks ( Anas platyrhynchos , Anseriformes), at day 12 in budgerigars ( Melopsittacus undulatus , Psittaciformes), and at day 13 in Laysan albatross ( Phoebastria immutabilis , Procellariiformes; Bride & Gomot, ; Jacob & Ziswiler, and bibliography cited therein; Fukui, ; Fukui, ; Rehorek et al, ). However, only the characterization of the developmental stages of some of these species (i.e., Gallus gallus , Hamburger & Hamilton, ; Coturnix coturnix , Ainsworth, Stanley, & Evans, ; Phoebastria immutabilis , Rehorek, Smith, & Beeching, ) are available in the bibliography, including our species under study ( Myiopsitta monachus , Carril & Tambussi, ), and it is on these species that we base our comparisons. We rely on that embryological stages are an appropriate tool for comparison between birds because they standardize homologous morphological events which are independent of incubation time and body size, so that changes in development trajectories when comparing species could indicate heterochronies (Starck, ).…”

“…The assignment of embryonic stages was performed based on descriptions made by Carril and Tambussi () and the nestlings' age was calculated using the length of the hindlimbs' digit III as proposed by Aramburú ().…”

“…Samples were fixed by immersion in 4% formaldehyde solution for 48 h and preserved in 70% alcohol. The assignment of embryonic stages (34 to 40+) was performed based on descriptions of Carril and Tambussi () and the nestling ages (from newly hatched to +21 days old) was calculated using the equation of the length of the hindlimbs’ digit III, as proposed by Aramburú ().…”

“…The only information previously available of any Psittaciformes is the skeletogenesis of the cranio–mandibular complex of the budgerigar Melopsittacus undulatus (Tokita ). The embryological developmental stages of the monk parakeet Myiopsitta monachus have been recently described (Carril and Tambussi ), providing useful information to evaluate sequence heterochrony in a comparative context with other birds. Our aim here is to determine the complete ossification sequence of M. monachus and to compare and contrast with observations of other birds available in the literature.…”
