Abstract Over the last past 25 year

Abstract Over the last past 25 years, Siamese fireback appear to have undergone a range extension,
expanding into higher elevation habitat in Khao Yai National Park, Thailand, where previously silver
pheasant predominated. To investigate this expansion, thought to have been triggered by climate
change and subsequent changes in forest microhabitat conditions, a long-term project was initiated.
The aim of this study was to investigate the altitudinal use of habitat of the two Lophura species. We
used colour bands (rings) and radio-collars to study the birds. In the areas where pheasants were
observed, we collected data on elevation and slope. The results reveal a distinct difference in habitat
use and elevation between the two species, although Siamese fireback were observed at higher
elevation, they prefer level areas while silver pheasant were found mainly on slopes. The results
indicate differences in suitable habitat for each of the two sympatric species which appeared to be
separated along an elevational gradient of approximately 15 degrees with a small overlapping area
where both species cohabit in close contact. However, all nests of both Siamese fireback and silver
pheasant were found on steep slopes (above 15 degrees). This is interpreted as a strategy to minimize
predator access to nests and to permit easy flight to avoid predation.

Oor die afgelope 25 jaar abstrakte Past, Siamese fire verskyn 'n Range Uitbreiding, het ondergaan
hoër hoogte habitat in Khao Yai National Park uit te brei na, Thailand, waar voorheen Silver
Pheasant oorheers. Uitbreiding van hierdie, te gewees het gedink veroorsaak deur Climate Ondersoek
Verandering en Forest Daaropvolgende veranderings in microhabitat voorwaardes is 'n langtermyn-projek geïnisieer.
Die doel van hierdie studie was om die gebruik van lugdruk habitat van die spesies Lophura Twee ondersoek. Ons
gebruik Kleur bands (ringe) en Radio-krae om die voëls te bestudeer. In die gebiede waar fisante is
waargeneem, ons het data oor opstand en helling. Duidelike verskil in die resultate toon 'n habitat
gebruik en opstand tussen die twee spesies, is waargeneem by 'n hoër Hoewel Siamese fire
opstand, hulle verkies gebiede, terwyl Silver Pheasant vlak gevind hoofsaaklik op hellings. Die resultate
dui verskille in geskikte habitat vir elk van die twee spesies wat simpatriese blyk te wees
'n Elevational Vervreemd saam met 'n helling van ongeveer 15 grade oorvleuelende klein gebied
waar beide spesies in noue kohabiteer Kontak. Maar al neste van beide Silwer en Siamese fire
Pheasant gevind op steil hellings was (bo 15 grade). Dit word geïnterpreteer as 'n strategie om die minimum te beperk
Predator Neste en om toegang Permit om Maklik Flight om predasie te vermy.
