Pytelia monteiri Hartlaub, 1860, Proc. Zool.
Soc. London. P111, pl. 161.
Monotypic: Clytospiza monteiri - generic name Greek: klutos,
splendid, beauteous; spiza, a finch; specific name after John Monteiro
(d.1878) collector in Angola, 1860-1875, and author.
DESCRIPTION
Length 13 cm (5 in). The sexes differ. The male has the entire
head dark slate grey except for a bright vermilion or orange-red median
stripe from the middle to the lower throat. The mantle, back and wings
are a dull dark earth brown. The underwing coverts are barred chestnut
and white. The rump and upper tail
coverts are dark orange red. The tail is brownish black. The
breast and underparts are rich chestnut brown, sometimes tinged with red
on the ventral area and under tail coverts, and spotted and barred with
white. Most feathers of the upper breast and flanks have two paired roundish
white spots and occasionally
two smaller and fainter spots nearer the base of the feather.
The spots intergrade into bars, usually two on each feather, on the belly,
lower flanks and under tail coverts. The irides are blood red, dark red
or reddish brown. The eye-rims are bluish. The bill is black, with the
base greyish blue. The legs and feet are fleshy
brown.
The female has no red on the throat but has a dull white median
stripe that runs right up to the base of her lower mandible. The orange-red
of her rump, the chestnut of her underparts and the grey on the sides of
her head are paler than in the male. Juveniles are a lighter and less greyish
brown on the upperparts with the
head a more brownish grey. The underparts are a duller and paler
chestnut brown without white markings apart from indistinct whitish barring
on the belly, ventral area and under tail coverts. The rump and upper tail
coverts are dark rusty orange. Young males have the grey of the head and
the chestnut of the
breast darker than young females. Three-day-old nestlings have
dark skin and quite profuse pale down. Their mouth markings consist of
five black spots on the yellow palate, a black band, narrowing centrally,
across the flesh-coloured tongue and a black crescent inside the lower
mandible. The swollen bi-lobed
gape flanges are white or white externally and yellow on the
inside. There is a black spot on the inside of the gape, at the base of
each mandible.
FIELD GUIDE
A small dark grey and dark brownish bird with a red rump and
blackish tail and diagnostic chestnut-brown, white-spotted breast and underparts.
The tail is noticeably fan-shaped when spread and the red rump and upper
tail coverts are conspicuous as the bird flits into cover.
VOICE
The following is all taken from Goodwin (1982). The close contact
call is a repeated vay, vay, vay… which is intensified and tends to be
uttered in longer series as a distance contact call. Young that have recently
fledged utter a loud eek, eek, eek that enables the parents to locate them
when they hide in cover.
The alarm call is a hard-sounding Sylvia-like tek. The song
of the male, which appears to be only courtship-oriented, is a variable
series of notes, difficult to describe and unlike that of any other estrildid.
It has been likened to the ‘crackling’ of Bishop weavers, Euplectes species.
DISTRIBUTION
Southeast Nigeria, Cameroon, southern Gabon, southern Republic
of the Congo, Cabinda and northwest Angola; also the Central African Republic
to central and northern Democratic Republic of the Congo, extreme southern
Chad, southern Sudan (north to Bussere), west and southern Uganda and western
Kenya (from Busia and Mumias Districts south to Siaya, Ng’iya and Akala).
STATUS
Uncommon or locally common.
HABITAT, GENERAL BEHAVIOUR AND FEEDING
It is found at 1000-1500 m inhabiting savanna with tall grass
and shrubbery, forest glades and edges, moist brushland and overgrown cultivated
areas (Goodwin 1982: van Perlo 1995; Zimmerman, et al., 1996). It
is usually seen in pairs or small parties (most likely family groups)
low down near ground cover
(Clement et al., 1993; Restall 1975; Zimmerman, et al., 1996).
It feeds primarily (probably entirely) on the ground, where it moves
with long quick hops, in a horizontal stance. It is known to take
grass seeds, insects including termites, and spiders (Goodwin 1982).
COURTSHIP DISPLAY
Goodwin (1982) relates that the courtship display is like that
of the Peters’ Twinspot Hypargos niveoguttatus except that the male’s movements
are more jerky and less graceful. While carrying a blade of grass or feather
in his bill and singing at the same time he performs long hops around or
half around the female, usually with his tail spread and angled towards
her and his head alternately pointed upwards at an angle of about 70º
and bowed towards the female at an angle of about 30º. The display
may occur without any nesting symbol or it may be held only at the beginning
of the display. The female may perform the same
movements in synchrony with her mate or remain passive. If she
solicits, in the usual manner with quivering tail, copulation follows.
NESTING
Chapin (in Goodwin 1982) found the species breeding in old nests
of the Bronze Mannikin, Lonchura cucullata, and other (unidentified species).
These old nests had been re-lined with hair, feathers, soft vegetable material
and, without exception, also with some cast snake skin. Zimmerman et al.,
(1996) mention that it is said to also use old weaver nests for roosting
and nesting in. Small domed nests have also been described which, presumably,
were built by the Brown Twinspot itself. Breeding takes place at the end
of the rains and the beginning of the dry season. In the Uelle district
of the Democratic Republic of
Congo it breeds from August to December; in Uganda from June
to October and in southern Sudan in September (Goodwin 1982).
CAPTIVE OBSERVATIONS
This is a very rare and probably non-existent species in UK
aviculture (and the USA?) and I can find no breeding records for it. Restall
(1975) says that specimens are reputed to be shy but that it has been bred
several times in South Africa. Goodwin (1982) gives the only observations
I can find and these are: it
will take various millets, and some individuals will also take
canary seed. Soaked spray millet and chickweed are also sometimes taken,
sometimes soaked seed and greenfood are only taken at breeding time. Ant
pupae, whiteworms and the half-ripe seeds of various unidentified grasses,
and home-grown millet were eagerly taken when the adults were rearing young.
Individual birds have been
observed swallowing seeds without first dehusking them.
It will build its own nest, which may be round or more or less elongated
in shape depending on where it is sited, among twigs or bushy cover, on
the remains of an old nest or on a rough platform of grass, etc., purposely
placed for such. A nest-box has also been utilised. Various nesting materials
may be used but when ample choice has been given the nest was always mainly
built of broad blades of grass, preferably green, and wheat, and thickly
lined with feathers. Throughout incubation and the brooding of nestlings
the male takes feathers and pieces of
green grass into the nest. The large side entrance of the nest
is always screened or ‘closed’ by a feather while eggs and young are being
brooded. The male alone collects material but if the female
is in the nest she may take feathers from him and position them. Up to
5 feathers have been known to be carried at a time. A clutch of eggs number
4-6 and the incubation period is around 13 days. The young fledge at 19-21
days.
Being so rare and with so little known about it this species
must only be kept by the most dedicated and accomplished aviculturists.
Hailing from tropical Africa its acclimatisation must be undertaken with
care, with temperatures not being allowed to drop below 22º Celsius
(70ºF.).
