Colymbus holboellii (Reinh.). 
Holboell's Grebe. 
Rare transient visitor. 
According to Stearns (’83, p. 17) this grebe is “not rare in*spring 
and fall” on the southern Labrador coast. Pie also states that it 
occasionally breeds, but this may be considered somewhat doubtful. 
He refers to it in one place as the “Whabby” a name given on the 
Labrador coast to the Red-throated Diver, as he himself recognizes. 
Colymbus auritus Linn. 
Horned Grebe. 
Rare transient visitor; possibly breeds. 
The only definite record for this bird in Labrador is of a specimen 
taken at Fort George, James Bay, by R. Bell (’83). Turner speaks 
of having seen a single grebe “in a tidepool at the mouth of the Kok- 
soak River, September 15, 18S2” but he was unable to determine 
whether it was this species or C. holboellii. 
Gavia imber (Gunn.). 
Loon; “Loo.” 
Common summer resident. 
The Loon is well distributed throughout Labrador, although no¬ 
where very abundant. It is found among the lakes of the interior 
and along the entire coast of the peninsula, north into Hudson Strait, 
especially in the deeper fiords and inlets. 
Cartwright, on his arrival at Cape 1 Charles on July 30, i770, says: 
“As none of these people, who were employed in the boats, had ever 
been in this part of the world before, they were greatly terrified with 
the continual crying of the loons, believing them to be Indians.” 
Cartwright records the first Loons in 1775 on April 14th; Audubon 
speaks of having “witnessed the arrival of some on the coast of Labra¬ 
dor, after they had crossed the Gulf of St. Lawrence, as late as the 
20th of June.” Various observers agree that they nest exclusively 
on the borders of the freshwater lakes, large and small, that are so 
numerous on the mainland. Low and others who have traversed the
