While the hen is sitting, the male bird remains somewhere in the neighbourhood, and gives timely warning of the approach of danger; when the eggs are hatched, he accompanies his mate, and shares in the work of teaching the young to shift for themselves--a lesson which they begin to learn at once. The food both of old and young birds is, to a great extent, insects. The young are especially fond of ants and their pupæ or larvæ. During the year 1860, in which there were no broods of Partridges, I was much struck by the fact that stubble-fields abounded, to an unusual degree, with ant-hills. In ordinary seasons, these are found torn to pieces and levelled. This year, scarcely one was touched; and even at the present time, the end of October, winged ants are far more numerous than they usually are at this time of the year. Besides insects, Partridges feed on the seeds of weeds, green leaves, grain spilt in reaping, and on corn which has been sown. This last charge is a serious one; yet, on the whole, it is most probable that Partridges do far more good than harm on an estate, the insects and weeds which they destroy more than making amends for their consumption of seed-corn.
I might fill many pages with anecdotes of the devotion of Partridges to their maternal duties--their assiduity in hatching their eggs, their disregard of personal danger while thus employed, their loving trickeries to divert the attention of enemies from their broods to themselves, and even the actual removal of their eggs from a suspectedly dangerous position to a place of safety; but with many of these stories the reader must be already familiar if he has read any of the works devoted to such subjects.
The number of eggs laid before incubation commences varies from ten to fifteen, or more. Yarrell says, 'Twenty-eight eggs in one instance, and thirty-three eggs in two other instances, are recorded as having been found in one nest; but there is little doubt, in these cases, that more than one bird had laid eggs in the same nest.' This may be; but I find in a French author an instance in which no less than forty-two eggs were laid by a Partridge in captivity, all of which, being placed under a hen, would have produced chicks, but for the occurrence of a thunder-storm accompanied by a deluge of rain which flooded the nest, when the eggs, which all contained chicks, were on the point of being hatched. The average number of birds in a covey is, I believe, about twelve; quite enough to supply the sportsmen and to account for the abundance of the bird.
