#SugarbirdSunday…The delightful display of the Cape Sugarbird! The male of these fynbos endemics have striking tail streamers, & use a large “bump” shape on the edge of one of their flight feathers to make a loud whirring sound with forceful flapping, along with their raspy song, to attract females & defend their territories. #sugarbird @avibase #fynbos #endemicspecies #birdbehaviour #birding #birdtherapy #birdsofsouthafrica #scicomm #promerops #promeropidae #birdphotography #gardenbirds @friends_of_marloth (at Marloth Nature Reserve) https://www.instagram.com/p/CO737CNg0VQ/?igshid=1pdpaj91g92z7
