Birds of the Upper Muonio River. 73 



Chelidon urbica. Martin. 



Very common round the houses, where it is encouraged 

 by the Finns, who nail up thin planks under the eaves to 

 support the nests. It arrived on the 25th of May, when the 

 river was still frozen and the land was covered with snow. 



Cotile riparia. Sand-Martin. 



The northernmost colony of this species noticed was in 

 68° 25' N. lat., below Ainettivaara, where there was a cliff 

 of sand above a bend of the river. The eggs were laid in 

 the last week in June. 



Passer montanus. Tree-Sparrow. 



\Ve saw five individuals of this species at Leveavuopio on 

 the 28th of May, and one of them stayed for a few days, 

 but disappeared early in June. We did not notice them 

 breeding. 



Fringilla moxtifringilla. Br ambling. 



The Brambling was very common in the birch-woods, both 

 low down in the vicinity of the river and up the hills as 

 far as the birch-growth extends. It arrived on the 24tb of 

 May and by the 26th was generally distributed. We found 

 the first eggs on the 15th of June, but took fresh specimens 

 late in July. Seven in a clutch were not uncommon. 

 They vary greatly in size and type, and one of a clutch 

 is often very much larger than the rest. 



Linota linaria. Mealy Redpoll. 



This species is common in the tall willow-scrub, and 

 especially frequents islands in the lakes and rivers. It is a 

 late breeder and we did not find eggs till the 18th of June. 



Pinicola enucleator. Pine-Grosbeak. 



We did not observe this species in the birch-region; it 

 appeared to be confined to the fir-region, where it was fairly 

 plentiful. Small flocks arrived at Ainettivaara on the 

 9th of May, and were all in pairs the next day. At this 

 season the birds were very tame and we could approach so 

 near as almost to catch them by the hand. The first egg
