Studies On Breeding Of Reintroduction Black-Necked Bar-Tailed Pheasant (Syrmaticus Humiae) By Radio Tracking

Reintroduction is one of the most important ways to save the endangered species. A primary study on the reintroduction of Syrmaticus humiae was conducted in Cenwanglaoshan Nature Reserve, from April 2004 to July 2005. We studied the breeding biology of Syrmaticus humiae during the period April 2004 and July 2005. The main results are as following:1. The flocking behavior of Syrmaticus humiae is obvious in winter. There exist 3 flock patterns in the group of Syrmaticus humiae, i.e. male group, female group and mix group. The average size of all group observed is 2.3 birds. The group size was also influenced by some other factors, such as habitat and group structure. With breeding season coming, the group will be dismissing.2. The courtship display of Syrmaticus humiae was divided into two types: the frontal courtship display and the side courtship display. The behavior of the courtship display of Syrmaticus humiae is beginning to show every year February and it reaches climax in the last ten-day period of Mary and lasts a month. The activity intensity of courtship display has an obvious peak during the breeding season, occurring between March and April, and has two peaks during the day time, between 6 ?30-8 ?30 a.m. and between 16 ?00-18 ?00 p.m. The weather has significant effect on the courtship display (Oneway ANOVA, P﹤0.05).3. The territories and territorial behavior of Syrmaticus humiae were beginning March, lasting the end of breeding season. The wedding system is typical male dominance polygyny.4. And totally 5 nests were observed. The average clutch size of the pheasant is 6.3(n=38). The interval time of egg lying ranges from one or two days. The female begin to incubate before day laying the last egg. Incubation time is 27d. Temperature in nest is (37.7±1.16)oC. The female incubate alone and leave nest for feeding everyday. Leaving nest behavior happened on morning, noon, afternoon, 53.84%, 23.08%, 15.35% respectively. The female have comparatively changeless feeling site. Linear return analysis shows the weather situation has significant effect on the length of feeding time (t=3.717, P=0.01). Mass of eggs significantly related with the day of incubation (F=21.847, P=0.000). The positions of eggs in nest are frequently changed during the incubation period. The female longs for the nest strongly.5. Totally 5 nests have been found in the field work, 3 nests located in coniferous forests, 2 nests located in shrubs. All nests built in the sunny slope and lower gradient, and all were near the...
