The November birds are much worn, and the pair taken on 
the 27th have the wing-feathers and tail almost bleached 
white. The January birds are moulting. 
The Common Miner was usually observed on the hanks 
in pairs, and breeds among the sand-hills, making a hole of 
about two or three feet deep. In a cavity at the end the eggs 
are laid on a bedding of dry rubbish, the full clutch being 
three. There is a clutch of three in Miss Binnacles' 
collection, taken as late as December 23rd, 1909.

wear, and the January bird is moulting, the old feathers

tips to the throat-feathers.
