Johann Matthäus Bechstein,
The Natural History of Cage Birds
“ Autumn is the time for taking birds in nets; some, attracted by a call-bird, or by food, come of their own accord into the trap; others, as the different species of larks, must be driven to the net; but spring is the best season for employing the decoy, or call-birds, concealed in cages, and also for catching25 the northern birds on their return from the southern countries to their own. It is the best time for observing the different sexes of these birds, for the males always arrive some days, or even a whole week, sooner than the females ”
