Specials: Bushmanland
Burchells
Courser
This
endemic is undoubtedly the most frequently missed special
in Bushmanland, and its elusiveness is attributable to its
nomadic tendencies and low population density. The best places
to search for it, and the recommended strategies, are given
on p.90. In the non-breeding season, large nomadic groups
may be seen in almost any open area. While today it is very
much associated with arid areas from the Namib to the Karoo,
the bird wanders widely, and small numbers move in winter
into the higher-rainfall wheatlands of the southwestern Cape,
and into the grasslands of eastern South Africa. It was once
even described as regular in western KwaZulu-Natal, although
it no longer occurs there.
Red Lark
This
little-known bird, whose nest was only discovered as recently
as 1986, is the only species whose global range is totally
restricted to Bushmanland. It is, however, reasonably common
in its localized sandy habitat. Red Lark occurs in a number
of colour forms, though recent research has shown that these
are not sufficiently different from each other to warrant
individual species status. Generally speaking, the rich reddish-backed
dunes form occurs on the red dunes in the northwest
of the region near Aggenys (see p.95), while the browner-backed
plains form is found in the east of the region
(around Brandvlei for instance; see p.89). The males engage
in conspicuous aerial displays, during which they call frequently.
Sclaters Lark
Largely
restricted to this region, Sclaters Lark is one of the
enigmatic specials of Bushmanland. Suggestions on finding
this inconspicuous bird, and its habitat preferences, are
offered on p.91. It is unique among local larks in that it
lays only one egg, a phenomenon shared by several other unrelated
species (such as Double-banded Courser and Karoo Korhaan)
that co-habit its harsh habitat. Parent birds undergo huge
thermal stress while sitting on the nest, which is situated
on exposed rocky plains. Once the egg has hatched, small stones
are placed in the nest to break up the chicks shape
and add to the camouflage. Although still locally somewhat
nomadic, artificial stock-watering points on farms must have
benefited this species as, conveniently for birders, it needs
to drink regularly.
Black-eared Finchlark
This
is a characteristically nomadic species that moves around
in large numbers in response to rain and often irrupts into
areas where the grass is seeding. Care needs to be taken in
identifying the females, which may resemble other larks and
finchlarks. Breeding must occur rapidly due to limited favourable
conditions, and males hover butterfly-like during their characteristic
display flights. The nest cup, lined with grass and distinctively
surrounded by an earth and spider-web mix, is usually built
at the base of a small shrub. Curiously for a lark, this species
sometimes nests in loose colonies.
