Una 'rareza' es un #ave que no vive en un territorio, y que aparece en él de forma excepcional o esporádica. En España, por ejemplo:
-Suirirí bicolor (Dendrocygna bicolor, pantropical)
-Petrel antillano (Pterodroma hasitata, Caribe)
-Ruiseñor azul (Larvivora cyane, Oriente)

Great news! Two nights ago, we captured a black-faced type of Pterodroma hasitata (435g) in a mistnet in Santo Antão. We are not sure if it was a breeder, which would be 1st record for E Atlantic. Check its typical tail and underwing pattern #CapeVerdeSeabirdProject #seabirds

Fantastic chumming day between Fogo and Cima #CaboVerde . A Black-capped petrel or #Diablotin #Pterodroma hasitata attended for just 2 min, but what a great two minuts! Is PTEHAS breeding in Cape Verde? Too much speculation I know. #seabirdersaturday #seabirds 📸 Herculano Dinis

Black-capped petrel (Pterodroma hasitata) breeds only in the Caribe, but two individuals were captured during its breeding period in Santo Antão. Amazing! Check the differences between the white-faced and black-faced types captured in 2016 and 2018 #CapeVerdeSeabirdProject

In #Dominica we seach for #diablotin nests with our #detectiondog Africa, but we also search for courtship areas were non-breeders vocalize at night!🔦

The #Diablotin team is working hard every day to find any evidence of this sps in #Dominica . Not much luck so far but we will keep visiting potential nesting areas with our #detectiondog Africa as well as potential aereal courtship areas! #Pterodroma #hasitata #expeditiondiablotin

For #WorldSeabirdDay we'll share a photo of our signature species from the Gulf Stream offshore from Hatteras, NC USA - the Black-capped Petrel - Diablotin - Pterodroma hasitata - dark faced individual, photo by Kate Sutherland

Not a great picture, but good enough to confirm another sigthing of one of our favorite species #Diablotin black-capped #petrel #Pterodroma hasitata 😍in the waters between #Fogo and #IlheudeCima #CaboVerde while provisioning the field team 👏📸 Herculano Dinis Associação Projecto Vitó
