WISE BIRDING HOLIDAYS LTD – AZORES: TERCEIRA & GRACIOSA TRIP REPORT SEP 2013
AZORES 2013 TERCERIA & GRACIOSA PELAGICS
1st – 6th September 2013
The following is a trip summary of birds and cetaceans seen during a trip to the Azores. I was
invited along by Peter Alfrey the founder of Azores Nature. Azores Nature is a not-for-profit
project with the aim of organising exploration/discovery trips to the Azores for serious
birders/naturalists. The main focus of the trip was to carry out a number of pelagic trips off the
island of Graciosa (the most northern of the Central Group) exploring the Bank of Fortune
where a number of exploratory pelagic have taken place previously.
In particular, the endemic Monteiro’s Storm Petrel was the focus of trip. Following the work of
various seabird scientists the Band-rumped Storm Petrel complex in the North Atlantic has
now been divided into 4 taxa. This is based on differences in vocalisations on breeding
grounds and on different breeding periods, “hot season” breeders in the summer months and
“cool season” breeders in the winter months. The 4 proposed species are as follows:
Monteiro’s Storm Petrel: Rare Summer breeder from the Azores
Grant’s Storm Petrel: Widespread winter breeder in North Atlantic
Madeiran Storm Petrel: Summer breeder from the Canaries and Madeira
Cape Verde Storm Petrel: Winter breeder from the Cape Verdes
Monteiro’s Storm Petrel is known only to nest on just two islets just off the island of
Graciosa. Birds breed during the 'hot season' and egg laying is believed to take place between
early May and early July, incubating just a single egg until as late as early August (Bolton et
al. 2008). Grant’s Storm Petrel is far more widespread with Azorean waters and breeds from
as early as August through until March in the Azores. Distinguishing these two species “at sea”
is clearly very difficult, but the timing of this trip was set to coincide with the end of the
breeding season for Monteiro’s Storm Petrel. Thereforel Storm Petrels in an obvious state of
moult at this time were assumed to be Monteiro’s Storm Petrels, whereas fresh plumaged birds
were assumed to be either, newly fledged Monteiro’s or ready to breed adult Grant’s Storm
Petrels.
Of course, there were plenty of other seabirds on the agenda with recent sightings of
Swinhoe’s Storm Petrel and Fea’s and Zino’s Petrel having been recorded off the bank of
fortune as well as some fantastic cetaceans encounters. The trip also allowed some time to
explore the island of Terceira, famous for its impressive list of nearctic waders throughout the
autumn period. Other key target species were the Azores Gull and the endemic races of
Chaffinch and Goldcrest, all potentially future splits.

HIGHLIGHTS OF TRIP
Monteiro’s Storm Petrel: Some excellent views allowing careful scrutiny of plumage & moult.
Swinhoe’s Storm Petrel: A single bird investigated the chum slick for around 5 minutes
Brown Booby: A great find by Pete and only the 3rd record for the Azores
Fea’s Petrel: A single bird gave great views as it investigated the chum slick.
Blue Shark, Oceanic White Tip, Common, Bottlenose and Atlantic Spotted Dolphins
and 2 unidentified Beaked Whales: The cetacean and shark life around the Bank of Fortune
is truly impressive with many highlights on a daily basis. At times, the sea was boiling with
dolphin activity and Blue Sharks investigated our chum!
This Monteiro’s Storm Petrel was one of many sightings that we enjoyed.
