Over 25 shorebird species have been seen at Barre de Portneuf. The highest one-day total of all shorebirds was 8,832 on August 21, 1995. If ‘bird days’ are considered – an estimate of the season total, that assumes daily turnover – then 182,501 shorebird bird days were calculated for the 1995 season.
The highest one-day total of any one species was 7,000 Semipalmated Sandpipers on August 22 and 23, 1994 (116,925 bird days, 1995). White-rumped Sandpipers also feed at the site in large numbers, with up to 1,000 birds present daily (> 500 regularly) during their long peak period, which lasts from early August to mid-September. Black-bellied Plovers pass through here from early summer into October, with their peak numbers occurring in the second half of August. Up to 650 birds have been recorded, and between 500 and 600 per day seen regularly. Additional common migrants are Semipalmated Plover, Ruddy Turnstone, Red Knot, Greater and Lesser Yellowlegs, and Sanderling. Uncommon migrants include American Golden-Plover, Pectoral, Baird’s and Least Sandpipers, Whimbrel, Hudsonian Godwit, Short-billed Dowitcher and Dunlin. Shorebirds that occur here rarely include Marbled Godwit, Western Sandpiper and Buff-breasted Sandpiper.
Large numbers of gulls and terns congregate on the sandbar, for both breeding and roosting purposes. The Portneuf sandbar, along with another sandbar located near Pointe-Lebel, are the only two sites where Parasitic Jaegers commonly come to shore, often to feed on shorebirds.
