Europe. It corresponds to the supply of water and also to the different florification 
of the Eucalyptus species. 
The bee-eater is a migratory bird. It certainly was common everywhere (absent 
only at Sunday Island) but at Derby, for instance, I saw it in greatest numbers 
in March and April. 
In Beagle bay it was extremely common in the month of July. In the evenings 
the birds met in a tree in order to spend the night there together. "They joined each 
other in thick clusters, and sat close to one another on a branch as many as could 
possibly find room on it. When one shook the tree, they flew out of the crown 
just like bees out of the hive.

The juvenal "''/s (2) differs from the adults in having a lighter plumage and 
considerably less black ornamentation. From the young bird mentioned above it 
differs by its paler dress and bigger black spots and above all by the grey parts on 
the head and the scapulares. 
The wing-coverts have no distinct spots and are light red-brown. The plumage 
is in its ornamentation more speckled than mottled (cf. the adults). The white spots 
of the primaries are tinged with rufous. Rectrices greyish brown bordered with black. 
Belly rufous-brown. The white on the throat less than in the adults, not bordered 
with black. Crown with a few black centres on the middle feathers, forming a black 
band along the crown. The two middle tail-feathers grey (growing out). The breast

The juvenal ”"/s (S) resembles the former, but has more black on the scapulares 
and the crown of the head.
