A few Canada jays often came into the village looking for scraps 

 around the feeding places of the dogs. The Indians had some dis- 

 like for jays in addition to their prejudice against them for stealing 

 meat. Their name for them is Titimhotom. 



Jays were encountered through the woods in situations indicating 

 pairs to be about a mile separated. On April 8 a pair appeared to 

 be courting, and during the latter part of April jays could often 

 be attracted by call and came in twos. Sometimes three appeared 

 together and on April 23 two males were called, and were collected 

 together. 



Among the specimens collected the largest testes were found in 

 those taken April 15 and 17, and smaller testes were found in those 

 taken after April 23. The earliest young birds just flying were 

 seen on May 28 and recent fledglings were occasionally seen in early 

 June. Presumably the eggs were laid between middle and late April. 



Old Crow and Anaktuvuk specimens of Canada jay had less brown 

 than P. G. canadensis, but matched satisfactorily with P. c. pacificus. 



Corvusjcorax principalis Ridgway 



Early in April one or two ravens were often seen searching for 

 scraps of dog food. At that time their flight was marked by calling 

 and maneuvering, but toward the end of the month linear flights 

 became more frequent, suggesting that nesting or feeding young 

 was in progress. No variation in the numbers of ravens was observed 

 which would suggest migration. 



The Indian name for this bird is Tatoo.
