Art. VII.—Additions
to the Avifauna of the Bermudas with diagnoses of two new Subspecies;
by A. Hyatt Verrill.
During a
recent collecting trip to the
Bermudas, from March 10th to May
9th, 16 species of birds were observed that appear not to have been previously
recorded:
Phaeton oethereus. Red-billed Tropic-bird. Several were seen on Harrington Sound in April.
Larus glaucus. Glaucous Gull. A large flock remained some time. Seen about the
islets in Harrington Sound early in March. Were regarded as something new by the
inhabitants.
Melanerpes Carolinus. Red-bellied
Woodpecker, Chab. Seen April 8th, on a Pride of India tree.
Passer montanus. European Tree-sparrow.
Locally common in Paget Parish.
Naturalized; resident. Probably introduced with the
English Sparrow.
Carduelis cardudis. European Goldfinch. Abundant
on the southern
and eastern parts of the islands,
especially about Hungry
Bay. Accidentally
introduced about 1885, from a wreck.
Previously recorded by Reid as an escaped cage-bird.
Spinus tristis. American Goldfinch.
Resident. Not uncommon. Intentionally
introduced about 1896, near Hungry
Bay.
Spizella monticola. Tree-sparrow. A flock
was seen several times at Hungry
Bay during the latter part of March.
Sitta Carolinensis. White-breasted
Nuthatch. Seen April 14th to 30th, on cedars at Harrington House.
Dendroica Pennsylvania.
Chestnut-sided Warbler.
Dendroica striata. Black-poll Warbler.
Dendroica Blackburnioe. Blackburnian
Warbler. The last three were seen in flocks of other
migrants, March 12th to 15th, at Hamilton.
Saxicola oenanthe. Wheatear. Introduced recently near St. Georges. Appears to be perfectly
naturalized. Previously recorded by Reid as a rare migrant.
Mimus polyglottus. Mocking Bird.
Resident. Introduced about 1892, at Bailey
Bay. Not uncommon at Walsingham and Paynter's Vale. Appears to
be now naturalized.
The following four species were identified from
the local collection in the Public Library at Hamilton: Orchard Oriole; Thrasher or Brown
Thrush; Blue Jay; Red-shouldered Hawk.
The abundant resident Ground Dove proves to be the
Bahama subspecies (Columbigallina passerina Bahamensis). It
always has a black bill.
The resident Bluebird is decidedly larger and brighter colored than the true sialis. It is a new subspecies.
Sialia sialis Bermudensis A. H.
Verrill.
Blue of the upper parts of
male brilliant purplish azure, a little brighter on rump; chin light
blue. Breast, sides and flanks deep purplish-cinnamon, much darker and richer
than in North American specimens. Female more brownish with brighter rump and
back than in the true sialis. Edge
of wing, at carpal joint, distinctly pure white.
Length, 6.75 to 7.5 inches; wing, 4 to 4.25; tail; 2.75 to 3.25. Nest
usually built in crevices and holes of cliffs; eggs usually pure white, rarely
tinged with greenish-blue.
The resident cardinal bird of Bermuda
also differs as a subspecies, from the American forms:
Cardinalis cardinalis Somersii
A. H. Verrill.
Adult male: Lower parts brilliant orange-vermillion, brighter and more
orange than in C. cardinalis. Upper parts are also clearer and brighter,
deep lake-red, with scarcely any gray on tips of feathers.
Vermillion of checks and crest brighter and clearly defined. Bill deep scarlet.
Female lighter than in cardinalis especially below; breast buffy yellow; belly almost pure white; upper
parts clear ashy gray; crest and ear-coverts strongly tinged with red; wings
and tail nearly as in the male.
Length, 8.75 inches; wing, 3.75; tail, 4.75; culmen, 0.80.
