I did not meet with it to the north of the Guadarratna
range, but know that it occurs sparingly in the neighbourhood
of San Ildefonso in Old Castile.
In general habits this bird appeared to us to resemble
the Common Nightjar, but there is a very perceptible
difference between the “ churring” notes of the two
species 5 their eggs are not to be distinguished by any
constant diversity of size or markings.
