Dietary biology of the Eurasian eagle-owl but none are heavier than the largest mammalian prey that eagle-owls have taken including greater white-fronted goose ("Anser albifrons"), bar-headed goose ("Anser indicus"), great cormorant ("Phalacrocorax carbo"), Himalayan snowcock ("Tetraogallus himalayensis") and demoiselle crane ("Anthropoides virgo"), all averaging around , the swan goose ("Anser cygnoides"), the common crane ("Grus grus") and the (between the dimorphic sexes) great bustard ("Otis tarda"). Eurasian eagle-owls have also hunted adult male western capercaillie, which average about , although usually the much smaller females, at , are more regularly taken. Although they rarely take domestic birds, the range of sizes killed is just as dramatic,
Ascochyta tarda will decrease in future decades because of climate change (Bucker Moraes W., Cintra de Jesus, W.J, de Azevedo Peixoto, L., Bucker Moraes, W., Morra Coser, S., Cecílio, R.A, 2012). This will also be an issue in Ethiopia where coffee farming is the source of income for approximately 15 million farmers in Ethiopia and as much as 60% of the current growing area can become affected (Moat, J., Williams, J., Baena, S., Wilkinson, T., Gole, T.W., Challa, Z.K., Demissew, S., David, A.P., 2017) Ascochyta tarda Ascochyta tarda or Phoma tarda is a fungal plant pathogen that causes dieback and leafspot on
