The study is done in the period between (February 20 and October 20) by using ten adult quail Coturnix coturnix (Linnaeus, 1758). The sections are preparing by paraffin method then stain in Harris haematoxylin-eosin. The histological aspects of spinal cord in quail (Coturnix coturnix) the white matter is in the outer part, while the gray matter is arranged in from of X represents its internal part, the dorsal region is called the dorsal horns while the ventral region is called the ventral horns and the central canal cavity, the spinal cord areas appeared as follows: The medial column, column of von Lenhossek, lateral column, dorsal magnocellular column and marginal paragriseal, columns are also called Hoffmann’s nuclei.

This study aimed to identify the alterations of liver in the quail (Coturnix coturnix) exposed by nanosilver particles.45 quail (females) were collected from agriculture research center in Abu-Ghraib, divided into (6) groups including: T1(12 quails were exposed to 4ppm), T2 (12 quails were exposed to 8ppm) and T3 (12 quails were exposed to 12ppm) of silver nanoparticles solution for 60 days. As well as three groups for control (3 females for each). Birds were dissected to isolate livers for histological preperations after fixation with Bouin's fluid, Routine stains Hematoxyline and eosin were used. Histological study showed that the structure of liver in a control groups consist of hepatocytes arranged radially cords around the central vein

The habitat type and food availability always influence the population size of many
organisms. Bird’s feeding pattern should be abstracted to complete avian community structure
data. The agronomy main research farm of Orissa University of Agriculture and Technology
is a well-managed multi-crop agro-ecosystem which provides a suitable ground for ecological
research. In a multi-crop farmland, the association of Barn Swallow Hirundo rustica Linnaeus,
1758, with the Indian mustard Brassica juncea (L.) Czernajew, 1859 crops have been
recorded for the first time while hovering only on this field. A flock of Barn swallows was
recorded in 32 field visits while flying continuously over the Indian mustard field after
flow

The esophageal morphology of domestic fowl (Gallus gallus domesticus) was investigated to fillthe dearth of information on the morphology of esophagus from available literature and help inunderstanding its digestive tract biology. The esophagus is under study as musculomembranous tubularshape, it began from oropharyngeal cavity and terminated on the proventriculus. The esophagus wasdivided into three regions are represented by cervical part, crop, and Thoracic part. Internal lining of theesophagus consisted of un-branched straight longitudinal folds The length of the cervical part, crop andthoracic part were 11.5 cm, 3.5 cm, 6 cm respectively.

    Three Spirurid nematodes: Amidostomoides acutum (Lundahl,1848) Seurat, 1918, Epomidiostomum uncinatum (Lundahl,1848) Seurat, 1918 and Tetrameres sp. Creplin,1846 were isolated from the stomach (provenrticulus and gizzard) of the shoveler Anas clypeata from central Iraq. A brief description, morphometric and meristic characters for the nematodes were provided.Incidence of the three nematodes discussed with pertinent literatures.

    Twenty-two of the Starling Sturnus vulgaris Linnaeus, 1758 were collected in Baghdad city during the period from January to September, 2014, and examined for endoparasites. Ten (45.45%) were found infected with either the cestode Passerilepis crenata (Goeze, 1782) (31.81%) or the nematode Dispharynx nasuta (Rudolphi, 1819) (13.63 %). Morphometric and meristic features for these worms were expressed. D. nasuta is recorded here for the first time from S. vulgaris for Iraq.
