“…As referred to the pecking behaviour, according to Newberry et al, (2007), in the wild, pecking is a natural behaviour that leads to the establishment of a pecking order in the group. While for the abnormal behaviours, captive environments can cause abnormality and several studies have already shown the effect of enclosure size in the behaviour of captive animals (Fisher at al., 1980;Estep et al, 1978;Innis et al, 1985;Hogan et al, 1988;Jensvold et al, 2001). Among of the examples are feather-pecking, toe and face pecking, anorexia and many others.…”

The behavioural patterns of six captive ostriches (Struthio camelus) werestudied at Universiti Malaysia Kelantan, Bachok Campus between July andSeptember 2014. The main purpose of the study was to determine thebehavioural patterns of ostriches in captivity to provide the useful informationfor better management action. The ostriches were observed daily for 11 hoursfrom 0700 hrs until 1800 hrs for 45 days by using the focal sampling technique.Six categories of behavioural patterns were observed namely resting,locomotion, ingestive, comfort, aggression and thermoregulation. The highestbehaviour observed was walking compared to other behaviours, while thelowest was running. The result of the study showed a significant difference ofbehavioural patterns of captive ostriches between different observationalperiods except for locomotion and aggression behaviours. The finding of thestudy showed that ostriches reared in captivity possessed similar behaviouralpatterns to those remaining in the wild, although some captive circumstancesimposed minor differences.

We present a stereotaxic atlas of the brain of the trumpet-tailed rat or degu (Octodon degus), an hystricomorph rodent native to Chile and one which has become increasingly popular as a research animal, among other things because of its use as a model for diabetic cataracts and its tendency to become hyperglycemic. The atlas contains 38 transverse and two sagittal sections of the brain covering pros-, mes-, and rhombencephalon, as well as diagrams of the brain's surface anatomy. It was constructed from brains of young adult male degus but can be used readily in studies of adult females, since there is no apparent sexual dimorphism in the brain size of this rodent. Ninety percent of 40 experimental lesions used to check the accuracy of the atlas were correctly placed. The fore- and midbrain of the degu are generally more compact than corresponding regions of the brain in the laboratory rat (suborder Myomorpha) and the guinea pig (another hystricomorph). The amygdaloid complex extends further forward in the telencephalon. Major mesencephalic nuclei and fiber tracts are more rostral in position. However, superior and inferior colliculi are much longer in degus than rats. The basic organization of the rhombencephalon is similar in degus and rats, although there are clearcut differences in the length or size of some hindbrain nuclei.
