Birds constitute a zoological group which is considered to be good indicator of balance and biological diversity. The aim this study was investigate the birds region on Tamanresset situated in south Algeria has an area 554.000 km2. Direct observations with camera pair binoculars, supported by ornithological surveys carried out progressive frequently sampling, each stations area, 44 bird species...

Adult male rose ringed parakeets were exposed to very long photoperiod (22 hr L: 2 hr D) and very short photoperiod (2 hr L: 22 hr D) daily for 60 days during different phases of the annual testicular cycle. Adrenal activities of the experimental birds were compared with that of parallel held natural photoperiodic birds. Marked atrophy of adrenocortical cells was noted in the glands of long pho...

Aim: To determine seroprevalence and haematological parameters of some wild and semidomesticated birds naturally infected with avian pox virus (APV). Methods: A total of 160 birds belonging to 12 species were used for the study.

Nesting cavities are often a limited resource that multiple species use. There is an ongoing discussion on whether invasive cavity nesting birds restrict the availability of this key limited resource. While the answer to this question has important conservation implications, little experimental work has been done to examine it. Here, we aimed to experimentally test whether alien cavity nesting ...

Gut microbial communities play a fundamental role in health and disease, but little is known about the gut microbiota of pet bird species. This important to better understand impact microbes on birds’ may also be relevant context zoonoses. Total genomic DNA samples from pooled fecal 30 flocks (4–7 birds per flock) representing over 150 six different species (two Passeriformes: Northern Mockingb...
