A "Coereba flaveola" posed on a flower collecting its nectar.
This bird is very present at "saintes" but there remains rather difficult
to photograph because it remains only little of time posed on these
flowers.

SCIENTIFIC NAME: Coereba flaveola.

Identification:
This remarkable small sparrow presents a plumage at
the contrasted colors. The wing cap, coat, back and covers are black.
The edge of the wing carries a very obvious white bar on the level of
the secondary remiges. The bright yellow tail is prolonged by a black
tail. The head is lit by a thick very apparent white eyebrow which
starts at the base of the nozzle and continues well beyond the eye.
The chin and the gray throat very clearly dissociate remainder of the
lower parts. The chest and the belly to the under-caudal covers indeed
display a plumage of a bright yellow. Pr elsewhere, the yellow belly
sugar bowl is recognizable with its fine, rather long nozzle and
clearly bent. The females are rather similar to their partners. They
are characterized some however by a cap slightly darker, a throat
blanchâtre, and a tail which displays a hue plus yellow-olive. The
youthful ones have a plumage duller than their parents and the whole
of their plumage appears more yellow-olive. Certain subspecies have a
plumage almost entirely black. At others, certain colors are absent or
slightly different.

Song:
Its song is characterized by a chirp and a cry aigü or
strident, with the manner of an insect.

Habitat:
The yellow belly sugar bowl is present in a broad part of the
Central America and south. Its surface of distribution starts in the
south of Mexico and extends until the south from Brazil and North from
Argentina, through all the continent sudaméricain. It lives the
majority of the islands of the Caribbean and one can also occasionally
find it on the coasts of Florida. The islands were undoubtedly
colonized by successive dispersions above the ocean, so that each
island has practically its own particular subspecies. In the
Caribbean, all these races can be gathered in two principal groups
which are officially recognized: the bahaméen group
includes/understands the Bahamas (race Coereba flaveola bahamensis),
the Cayman Islands (C F sharpei), the islands with broad of the
peninsula of Yucatan (c.f. caboti) and some small others. The
West-Indian group integrates Puerto Rico (c.f. portoricensis), Holy
Cross (c.f. newtoni), Barbados (c.f. barbdensis) and some islands of
less importance. Curiously, the very prolific yellow belly sugar bowl
misses of Cuba. One commonly finds this bird in the areas of low
altitude and seldom in the high forests. One can observe it with
heights varying of the sea level up to 1200 meters, but most of the
time, it remains in the plains below 250 meters. Taking into account
the large surface of its surface of distribution, the yellow belly
sugar bowl can occupy a large variety of habitats. It is present in
the opened meadows, the zones of cover, the rain forests thick and
even in certain arid areas. In spite of this large évantail of
choice, the sugar bowl can be especially catalogued as a bird of the
tropical areas which seeks the zones where it can remain under cover.

Behaviors:
Whereas the construction of the nest for the reproduction
takes one week, this sparrow can also work out into two to four hours,
at any moment of the year, a smaller nest and more coward to spend the
night. Often with the contact with the sticky liquid that is nectar,
the yellow belly sugar bowl appreciates the baths, in particular in
the water reserves accumulated at the base of the sheets of
broméliacées. It also rubs its nozzle in the branches pout to clean
it. Contrary to the hummingbirds, the sugar bowls are unable to carry
out the hovering above the corolla. For this reason, they must be
always perched while they are nourished. Many time, one can observe
them rather the head in bottom than in driving position.

always perched while they are nourished. Many time, one can observe
them rather the head in bottom than in driving position.

Nesting: The reproduction varies slightly according to subspecies'.
However, rather typically, the sugar bowl carries out in the long term
several brooded during the season of nesting which lasts five months,
of Mars to at the beginning of August. This one intervenes at the end
of the season dries and its coincide beginning generally with the
first precipitations which mark the beginning of the wet season. The
sugar bowl is a solitary bird. It does not adopt a territorial
behavior and courts the females without showing aggressiveness with
regard to the other males. The male and the female batissent each one
their own nest in the shape of sphere with a hole of input on the
side. They use vegetable sheets, grasses and fibres for the carcass
work. The interior is furnished with matters finer and as various as
of the wire, papers, the feathers and the cobwebs. These nests which
are useful for the rest are used during all the year and each sex
defends of them the direct accesses against the possible intruders.
Before the reproduction itself, the male spends its time singing near
its own nest and of that of the female, seeking to allure it. The
future partners share together several forms of ritual during which,
it face, are greeted mutually, turned their heads, scrape and flown in
a great number of directions. Before the female does not lay, the male
is held very close to it, adopts a protective attitude while they
nourish and collect the materials which will use for construction of
the nest of reproduction (which is different from the nest for the
rest) This one is placed at low height by the two adults who hardly
take the trouble to hide it. The female deposits there 2 or 3 eggs
white-crême, sometimes rosâtres whose shell is covered with reasons
brown-salmon which vary according to the area. After the laying, the
male takes its distances, becomes less attentive and turns over to
sing in the surroundings of its nest of rest with an aim of attracting
a new partner. It there little time still, everyone agreed to think
that the sugar bowl had only one partner, but from fort recently its
polygamy is recognized like a current practice. Although the male does
not take any share in incubation and that the greatest part of the
nourrissage and other care are carried out by the female, certain
males take part sometimes timidly in the feeding and the monitoring of
the young people. The females play the principal part however and
protect the small ones against possible the aggression from predatory
such as the ants, the rats or the snakes

Mode:
Primarily nectarivore, the sugar bowl with yellow belly
also nourishes fruits like ripe bananas, of spiders and insects such
as the flies, the coleopters, the caterpillars or the ants which it
captures under the sheets. It exploits the nectaries (producing sugar
glands) at the base of the sheets of the plants. In order to be
fertilized, much flowers need the insects, the hummingbirds or the
bats nectarivores to transport their pollen of one flower to the
other. With this intention, they attract the visitors by producing
nectar, that the latter must go to seek at the bottom of the flower,
thus filling, and without their knowledge, the service which is
required of them. This stratagem functions only if the bird passes by
the opening of the corolla and comes into contact with cheesecloths or
the pistil of the flower. The sugar bowl is a gourmet who regales
nectar. However, its nozzle is too short, contrary to that of goods of
the hummingbirds. On the other hand, it is sufficiently sharpened to
practise an incision at the base of the corolla and it reaches thus
directly its favorite drink. The subterfuge of the flower which offers
its nectar in exchange of the transport of its pollen is then
thwarted. The yellow belly sugar bowl always behaves like a true
pilferer. On certain islands of the Caribbean where it attends the
cities assiduously, it is so familiar that it does not hesitate to
flutter of table in table pourmanger of sugar

Hi Max, very excellent work. The bird is a new one for me so thankyou for the introduction. You have the bird in a great pose, with very excellent colour and you caught it in action, feeding. Your details are tack sharp on the bird, with good use of you depth of field to mute down the background. Your notes are incredible.

Thanks, John

Hi Maxime.
Thanks for interest and kind words. I also like your very nice shot. You managed to reflect a cute bird at so interesting moment on wonderful flowers. Colours are great aslo as well as the sharpness of the main subject. BG is so interesting too. I do not know how you have got such BG. It is a pity a bit that the tip of bird tail is cut bit it is not a point. Well done and TFS.
Alexei.

Not only is this an excellent photo, but your notes rank up there too. I have to agree that that the BG adds to the sharpness of the bird. The colors are brilliant and not lost in the daylight.
