sókn stendur nú yfir á tíöni capillarias-
is og öðrum orsökum dauðsfalla í fálk-
um á tímabilinu 1972—1982, til sam-
anburðar við niðurstöður B. Clausens
og Finns Guðmundssonar (1981).
Methyridine virðist geta slegið verulega
á fálkaveikina og ef til vill læknað
hana alveg. Má benda á, að hingað til
hefur orðið að aflífa fálka sem fundist
hafa lifandi með fálkaveiki á háu stigi.
Á því getur nú orðið breyting.

In this article capillariasis (frounce) in
Icelandic gyrfalcons (Falco rusticolus islan-
dus) and its causes is briefly discussed. A
wild Icelandic gyrfalcon, with pronounced
signs of capillariasis (Capillaria sp.) in the
throat, was treated subcutaneously with
0.2 ntg/kg body weight of a 90% solution
of methyridine (2 —[B-methoxyethyl]pyri-
dine). AU symptoms of the disease in the
throat disappeared in 6 days, and the bird
regained a healthy appetite. The number
of Capillaria eggs was 31.950 per g faeces
on the day of treatment, but fluctuated
between 900 and 23.000 during the next 14
days at which time the study came to an
end.
