Help me with Procellaria sp. ID from Chile
Posted: Tue May 08, 2018 2:29 pm
Hello NZ birders:
I need help with ID of these birds.
Both of them were observed past Saturday on pelagic trips in North and Central Chile, Arica (18°S) and Valparaiso (33°S).
I was present on the Valparaiso's boat. We observed a dark shearwater with a contrast between underparts and head. Initially, we think in the unusual Pink-footed shearwater (dark morph). Another possibility was the related Flesh-footed shearwater. However, this bird has few records in Chilean waters. At reviewing the photographs, we noted a yellow bill with dark tip, opening to the possibility of Procellaria sp. Remarkably, during all the trip we only sighting one Westland petrel in comparison with the abundant White-chinned petrels.
I don't have experience with Parkinson's (black) petrel, because this bird also has few records in Chilean waters. However, we haven't seen this plumage previously in Westland petrels. We observed moulting on Westland petrels between October-December in Chile.
Interestingly, our friends in Northern Chilean waters saw a bird with similar features. They think in Westland petrel.
I hope your help with the ID of these birds.
Many thank.
