This paper examined the seasonal variation in herd
size of Roan Antelope in Borgu Sector of Kainji Lake
National Park (KLNP). In the wet season months of
May, June and July; the average numbers of 49, 38
and 31 Roans were recorded. While in the dry season
months of April, January and March and December; the
average numbers of 79, 57, 56 and 53 Roans were
recorded. Herd size of 2 – 5 dominated with 64% in
the first year of study. In the second year of
study, the 2-5 herd size dominated with 63%. The
study showed that in the first year the 6-10 and 2-5
with 42 and 38% dominated. In the second year the
6-10 and 2-5 dominated with 41 and 38 %. The herd
sizes of 16 – 20 and 21+ were represented by 2.0%
respectively. Therefore in KLNP, herd sizes of 2 – 5
are commonly seen in the wet season while the 6 – 10
and 2 – 5 are mostly seen in the dry season.
