While the extent of AIV is quite reliable from bird-to-bird relative to nucleus RA, all of our anatomical work identifying the inputs to AIV is based on retrograde-labeling of neurons from VTA/SNc.
If observations for this study had been made in regions where there was a greater frequency of interactions between deep diving seabird species and albatrosses, it would not have been possible to obtain reliable estimates of bird captures during setting because seabird capture events would have occurred at a greater distance astern, potentially outside of the researcher's field of vision.
It has been argued that the cytochrome b gene gives reliable information in birds only for divergences younger than 9 million years [ 22], i.e. evolutionary events considerably younger than the evolution of most modern orders and families.
Irrespective of sex and of experiment, birds did neither differ in weight, nor in bill length (which provides a reliable estimation of a bird's strength), nor in age (see Table 1).
By hanging, the flower caters to the hummingbird's unusual skills – something the plant may have evolved to do because of the bird's reliable pollinating habits.
Previous efforts to create evolutionary trees of birds were hard pressed to find reliable places for some enigmatic living bird groups -- notably the hoatzin and the mousebirds.
Additionally, she said, stuffing the bird provides a reliable and convenient spot to test for overall doneness.
He wears glasses except to shoot, and has a bird dog so reliable that "when she was pointing a covey he patiently removed his glasses, slipped them into his pocket, and then flushed the birds".
For several decades, utilities and wildlife resource agencies have worked together to reduce detrimental impacts to birds while providing reliable electricity.
An unstuffed bird is much more reliable in the oven.
