When
an Isabelline Wheatear came hop, hop, hopping
By Taya F. Diaz
Wheatears belong to the order Passeriformes – the perching
birds and to the family Turdidae, to which chats and robins belong.
The three species of Wheatears that visit the country are vagrants;
that is they can be sighted one year but could go missing for many
years thereafter.
A
single Isabelline Wheatear was observed at the Bundala National
Park (at the far end of the saltern where visitors are allowed to
alight from their vehicles) on November 16, this year, at around
10.15 a.m.
There
was a burst of bright sunlight through some threatening rain clouds
at the time. The observation was with the aid of binoculars (10x40)
and through a telescope (20x60).
The
bird was first perched on a small rock 12m away. Then it ran across
the sandy bund in pursuit of a winged insect, which it caught and
devoured immediately. It had an upright stance very much like a
pipit but unlike a pipit it wagged its tail somewhat like a wagtail.
It was this strange behaviour that caught my attention. My hasty
field notes at the time were as follows;
Beak – dark black, sharply pointed
Lores – Slight broken black markings
Supercilium-faint
white
Tail-fanned out in flight revealing a broad black tail end and a
white base.
Overall body colour – sandy brown, no markings, like the body
colour of a silver bill
Feathered up to the hock joint. (i.e. all of the tibia covered in
buff coloured feathers.)
Running
was very vigorous; when it stood upright its tail almost touched
the ground.
Size–it was about the same size as a pipit but slightly bulkier.
Vocals– no callings were heard
Observations
time– had about 10 minutes of observation. Then it flew quite
speedily to another baulk in the saltern some distance away.
Number sighted-only one bird
We refered John Harrison’s field guide and compared my above
notes for confirmation of identity.
