HELMINTHS FROM WILLOW GROUSE ( Lagopus lagopus ) IN TWO LOCALITIES IN NORTH NORWAY.
A total of 77 adult and 123 juvenile willow grouse ( Lagopus lagopus ) from the island of Karlsöy, and 75 adult and 63 juvenile willow grouse from Sennaland on the mainland of North Norway were examined for helminths. Raillietina urogalli and Hymenolepis microps , and Ascaridia compar and Syngamus trachea were found. All four species occurred regularly in grouse from Karlsöy between April and September-October, but only H. microps was frequently found in birds from Sennaland. S. trachea only parasitised juvenile grouse.
