(1984) Francolinus pondiceriana interpositus Hartert.
THE NORTHERN GREY PARTRIDGE.
Francolinus ponicerianus interpositus, Fauna B. I., Birds, 2nd ed. vol v. p. 421.
The range of this race of Grey Partridge is North of that of the preceding bird, i. e., North of a line from Poona to the Godavery, from the South of Sind East to Bihar and Western Bengal through¬out the drier districts of Chota Nagpore to Rajmahal.
Birds from the South of Sind are somewhat intermediate but are nearer interpositus than to mecranensis. In the Punjab the Indus may be taken as the dividing line between mecranensis on the West and interpositus on the East. In Guzerat the birds approach nearer to true pondicerianus.
Having given the habitat of the subspecies, there is little to add to what has already been written as to the nidification and breeding habits of the preceding species.
The Northern bird seems rather fond of placing its nest at the bottom of cactus hedges but, for the rest, makes its nest and selects sites just as the Southern bird does.
Like that bird also it breeds over the greater part of the year, with two definite seasons, March to May and August to September, during which most eggs are laid.
The eggs may vary a little more than those of the other races in a large series and I have all degrees of shade, from a pale creamy buff to a deep warm buff.
Ninety eggs average 32.4 x 25.6 mm. ; maxima 35.8 x 20.2 and 35.6 x 27.4 mm. ; minima 30.2 x 24.8 and 30.4 x 23.0 mm.
