We calculated nest success for individual species when sample sizes were sufficient for analysis ([mayor que o igual a]5 nests per treatment) and for all passerines
combined to represent the suite of species utilizing southern Great Plains areas.
birds were seized by the Brazilian Institute of the Environment and Natural Renewable Resources in the interior and capital of Para State, Brazil.
The influence of nest-box area on clutch size in some hole-nesting passerines
Many birds are passerines
that become disoriented on overcast and misty or rainy nights during fall migration between Scandinavia and Great Britain, although some are seabirds (e.
The pattern of origin by fleshy fibers and insertion by aponeurosis for this muscle appears to be conservative in passerines
(Richards and Bock, 1973; Donatelli, 1997; Donatelli and Marceliano, 2007).
Using the standard Mayfield methodology for nest fate monitoring, we monitored all nests encountered belonging to the five aforementioned passerines
(Mayfield, 1975; Johnson, 1979).
Phenological studies in Croatia were up to now restricted to the spring arrival of breeding passerines
(Dolenec, 2003; Kralj and Dolenec, 2008; Dolenec et al.
Mainly water fowls of Asia are responsible for this infection including: gulls, ducks, passerines
, and waterfowl species.
The overall nest predation rate across all species was 36% and was lowest in the five most common ground-nesting passerines
(27% across species) and highest in mallards (50%) and the four most common above-ground and shrub-nesting species (44% across species) (Fig.
To evaluate the potential of these passerines
to infect vector mosquitoes, we compared reservoir competence index values, which predict the relative number of infectious vectors, i.
Birds -- including passerines
, goshawks and gulls -- and mammals like soay sheep, red dear and polar bears, have also trended toward less bulk.
ABSTRACT--High nest predation rates are one of the main sources of nesting failure in passerines
