The delayed growth in our birds indicates that our experimental protocol clearly affected the overall development of the young, and it is conceivable that this impact also extended to the development of the birds' brains.
Aside from anatomical differences such as long bony tails, clawed hands, and teeth, the slow development of the first birds would have made their biology appear unfamiliar to ornithologists.
Although the decision-rules used to establish the four categories from these conservation vulnerability scores are arbitrary, they are based on conservation categories established through expert review to capture the same concepts embodied in our risk-responsibility categories as part of the development of PIF bird conservation plans [12].
If genetic diversity affects the development of the vocal apparatus and/or bird's body condition, song performance may be directly correlated with individual genetic diversity as a result.
Extended surveillance in Imperial County by the Imperial County Health Department, Coachella Valley Mosquito and Vector Control District, and University of California, Davis, and the development of a dead bird surveillance program by the California Department of Health Services during 2002 are examples of new programs that proved useful in tracking WNV during 2003.
The preference for running is also a point of similarity, and seems graphically to illustrate the first stage in the development of a flightless bird.
In a population of house sparrows, Passer domesticus, in Kenya expanding inland along corridors of human development (roads), the birds at the leading edges of the range expansion showed greater responsiveness of the adrenocortical responses to acute stress and enhanced exploratory behavior.
Landscapes of the Four Seasons, which was remounted as a hand scroll, echoes the new development of bird's-eye view composition exemplified in the work of Li Tang.
Interdisciplinary Connections: Geography – A text timeline of both animal and human developments in the H5N1 strain of the bird flu virus is available at //www.who.int/csr/disease/avian_influenza/Timeline_15.02.pdf.
To facilitate the acquisition and analysis of the continuous recording of song development of individual birds, we have developed an open source software program that automates much of the data acquisition, feature calculation and database handling-Sound Analysis Pro.
