Earliest sightings were on 15 June (1991, 1997) and latest on 20 August 1993. Belugas were observed on 25% of open water days in June (n= 182), 13% in July (n = 279) and 1% in August (n = 223). The proportion of open-water days on which Belugas were seen peaked between 21 June and 4 July (Figure 2), when Belugas were seen on 34% of days (n - 126). They were seen on only 17 days after 10 July (4%, n = 429). Numbers. The highest June total was 1802, in 1998, and the highest July total 500, in 1994 (Appendix 1). The largest number recorded in a sin- gle day was 500, on 26 June 1998. Mean numbers sighted on days when at least one was seen ranged from 1-300, with averages of > 100 recorded for 17- 19 June, 23 and 25 June, 7, 8 and 10 July (Figure 3). Behaviour. Beluga that were travelling were usu- ally in distinct groups of 3-10 animals, spaced 50- 250 m apart, but moving within a relatively narrow corridor that passed 50-500 m from the tip of the camp promontory. Groups of more than five animals usually contained both adults and immatures: soli- tary adults were sometimes seen, but solitary imma- tures were rarely observed. Several records after mid-July involved single females with small calves (< half body length). Foraging animals also tended to be in distinct pods of similar size, but some aggrega- tions of up to 200 formed in the cove to the east of camp, where they frequently milled about and vocal- §^ â a â o o o 2 (0 -S o c o o O Beluga occurrence, Coats I., 1984-98 1111111111111 n.
