| The cloacal and genial glands were chosen because they release pheromones used in mate attraction or courtship. |
|
| A current theory is that the eggs are ovulated through the cloacal pore and are expelled under pressure by muscular contractions. |
|
| Birds were mist-netted or caught in seed-baited traps and sexed by examination of the cloacal protuberance. |
|
| But most birds and Sphenodon lack intromittent organs and transfer sperm by cloacal apposition. |
|
| Little is known of their reproductive biology, but the lack of both spermatheca in females, and cloacal glands in males, suggests external fertilization. |
|
| We also provide information on cloacal protuberance size as it pertains to mating behavior and sperm competition. |
|
| Males can be identified quickly by giving the area forward of their cloacal opening a gentle pressure. |
|
| Adenoviral particles were found by electron microscopy in the cloacal contents of the female Taita falcons but not in the male falcons. |
|
| Of the 10 chicks hatched from artificially incubated eggs, one 5week-old, hand-fed, Indian ring-necked parakeet had a positive cloacal swab. |
|
| Limited decreases in oropharyngeal and cloacal viral shedding and mixed results were attained when looking at seroconversion. |
|
| Oropharyngeal and cloacal swabs tested positive for influenza A virus H5N8 by real-time reverse transcription polymerase chain reaction. |
|
| Other species, such as the side-necked turtles of Australia, cope by using specialised cavities in their rear, known as cloacal bursae, to draw in water and remove the oxygen. |
|
| However, WNV viremia was sufficient, in theory, to infect mosquitoes, and oral and cloacal shedding of the virus may increase the risk of infection to other waterbirds. |
|
| Emily was born with Cloacal Anomaly, a rare condition which means she has poorly functioning kidneys and had to have one of them removed. |
