: Several observations show that parents remain with the young
until it, or they, are nearly full grown. Both parents accom-
panied a young bird on Bouchie Lake at least as late as August 18,
and a pair accompanied two young on Edy Lake at least as late as
August 30. However, at Quanstrom Lake on September 3, a young bird
was accompanied by only one parent.

Arctic Loon--Gavia arctica (Linnaeus)

; Mr C. D. Muirhead made note of a small loon with patch of
white on the head swimming in an open stretch of water in the
Bulkley River during the winter of 1933-34. The arctic loon is
known to occur as a transient in central British Columbia so that
this sight record Based on the above description is considered ac-
ceptable

Red-necked Grebe (Holboell Grebe)--Colymbus grisegena (Boddaert).

This was the commonest grebe and was found nesting, or accom-
panied by young, on many of the lakes visited. At Puntchesakut
Lake several were heard calling on May 7, and thereafter some were
seen or heard daily until I left the region on Jume 5. It was
still conspicuous when I returned there at the end of August. The
majority on this lake were transients associated with other migrat
ing grebes and diving ducks that assembled usually far out from
shore. The largest numbers seen together in one day were le on
May 24 and 25+ on September 3.

Two pairs nested on the lake and these were together on their
territories as early at least as May 10. The territory in each
instance consisted of a small bay with a sedge marsh at the end.
One nest, about 18 inches in diameter, made of rotted sedge and
some water moss, floated amongst new growth of sedge about 10
feet from the outer edge of the marsh. It contained one egg on
May 27. This nest was deserted and the pair built another one of
the same material 14 feet from the first in a situation that seemed
identical, except that the nest rim at most of its circumference
touched or overlapped yellow pond lily leaves. It contained one
egg on May 30. Another nest identically constructed, and empty on
May 28, was built up from the root system of a sedge clump. It
also was surrounded by yellow pond lily leaves

Pairs of Holboell grebe, undoubtedly nesting, were found on
other lakes in the Baker Creek region, namely, Tiltzarone Lake,
