142 BIRDS OF TIER R A DEL FUEGO 



This is the commonest Gull met with, not only on the coast but 

 inland. It is particularly aggressive to man, making for one at 

 sight, following one overhead, and barking like a dog " Wau- 

 ivan-ivauJ' At other times, it gives utterance to a long-drawn 

 plaintive ^'' K-iv-i-i-y-u.^^ 



Large numbers congregate in the neighbourhood of settle- 

 ments, and there spend their days fighting over offal. They 

 breed on islands in fresh water lagoons, in places sometimes 

 impossible of access by all ordinary methods. 



Azara mentions the "voz muy desagradable " of this bird, 

 and says " abunda infinito en el Rio de la Plata." 



Darwin says : — '^ It abounds in flocks on the Pampas — 

 sometimes even as much as fifty and sixty miles inland. 

 Near Buenos Ay res, and at Bahia Blanca, it attends the 

 slaughtering-houses, and feeds, together with the FoJyhori 

 and CatharteSj on the garbage and offal," 



Capt. Abbott says it is a common resident in the Falk- 

 land Islands, though many leave in winter. In the beginning 

 of December they commence breeding in large flocks, laying two 

 eggs near the beach, or on a small island, without much attempt 

 at a nest. In September they appear in large numbers, many of 

 them immature. During the winter he observed few, and these 

 all old birds.
