Coco)
Observations: This species was
found in all habitats of the island,
both adults and juveniles.
Noteworthy is the abundance of
young birds in the vicinity of the
Chatham Bay station. Undoubtedly
this is due to the feeding of these
birds by both park employees and
visitors. The future of this specific
population (around the ranger station)
therefore must be considered
doubtful. There are studies on the
population of this species, amongst
which we cite: Montoya (1991),
Sherry & Wemer (1984b), Smith &
Sweatman (1976), Werner & Sherry
(1987).
 Spiza americana
 (Dickcissel) (Sabanero arrocero)
Observations: One breeding adult
was seen on the 25th, 26th, and 28th in
the grassland above Chatham Bay.
This species was observed previously
on the island by Sherry & Werner
(1984a), between November 1983
and September 1984.
 Dolichonyx oryzivorus
 (Bobolink) (Tordo arrocero)


Observations: A group of five males
in breeding plumage foraging in grass
at the soccer field in front of Villa
Beatriz, Wafer Bay, was seen on 26
and 27 April. The first sighting of
this species dates from April 1930
(Chapin cited by Slud 1967), later by
Slud (1967), Grant & Grant (1997)
and others.
 Icterus galbula
(Baltimore Oriole) (Bolsero Norteo)
Observations: One male was seen at
the soccer field at Wafer Bay on the
aftemoon of the 26th There is no
doubt as to the identification of this
bird, as the black head, diagnostic of
the male of the species, was seen
clearly. Two females were sighted
previously at Wafer Bay between 19
and 21 April 1963 by Slud (1967).
 Icterus pectoralis
 (Spotted-breasted Oriole) (Bolsero
 pechimanchado)
Observations: This species was seen
and heard various times at Wafer Bay
between 25 and 28 April by park
guards and other observers (Robert
Chaverri, 2005). They observed an
adult and three immature birds in
characteristic plumage in the vicinity
