bustard feather

This is the feather referred to recently. Little bustards moult their first 5 primaries around June/July. This looks like primary 1. It's the second one I've come across on the Lairiere plains in the last couple of years and the nearest I've got to seeing a bird! I was on the plains at sunrise yesterday (a bit nippy) but the only birds visible in the mainly cropped fields were stone curlews and skylarks.
