This may have influenced how buffaloes moved in the second year. Many people think the Great Migration happens only once a year, however it happens all year, with each season offering a unique wildlife experience. More data are needed in order to understand the observed movements and elicit any consistent patterns in the Mwagusi and TelekiMboga herds. Halley D, Vandewalle M, Mari M, Taolo C. Herd-switching and long-distance dispersal in female African buffalo Syncerus caffer. 2013;4:art51. The shortest daily distances traveled occurred in the wet season in AprilJune (mean 3.6km, SD=1.61.8km). 2e) appeared to switch herds and join the Mwagusi buffaloes (SAT 1494 and 1498, Fig. The comparison of usage and availability measurements for evaluating resource preference. The First Great Migration (1910-1940) had Black southerners relocate to northern and midwestern cities including: New York, Chicago, Detroit, and Pittsburgh. The latter two vegetation types were only present in the wildlife management area adjacent to the park, where SAT1497 spent part of a dry season and an entire wet season (Fig. Ruaha National Park, Tanzanias largest national park, is a part of the Rungwa-Kizigo-Muhesi ecosystem and covers an area of 20,226km2 [33].

CAS Females appear to exhibit a sort of "voting behavior". animal migration. Calves of both types have red coats. The probability of space use was estimated for individual buffaloes using Brownian Bridge Models (BBMM) using the packages BBMM in R [35]. In the dry season, the buffaloes selected habitats at lower elevation and in more rugged terrain closer to the river compared to the wet season (Table2, Fig. Coppolillo P, Clifford DL, Mazet JAK.

Rasters and shapefiles of the space use, as an estimate of the home ranges, were created with the R-packages rgdal, maptools, and raster [35]. Buffaloes are water dependent [11], and access to water determines which areas can be utilized by buffaloes in the dry season [6, 12].
