The Lace-necked Dove — SCHWARTZ and Schwartz 
101 
Solanum mdtflorum or popolo, grows 
occasionally in zones B and Di but commonly 
in zone Ci, particularly in old pineapple fields. 
The fruit and seeds of this indigenous species 
of the Solanaceae comprised 10 per cent of 
the diet and occurred in 19 (13 per cent) of 
the crops and 11 (15 per cent) of the gizzards. 
Field observations show that doves often 
gorge themselves on these succulent fruits, 
which are available all year. It is possible that 
moisture provided by this fruit may entirely 
eliminate the need for surface drinking water. 
Popolo is also an important food of pheas- 
ants {Phasianus torquatus Gmelin and P. 
versicolor Veillot) in Hawaii. 
Lantana Camara L. is an exotic verbena 
which accounted for 9 per cent of the diet. 
The fruits and seeds were taken in only 7 
(4 per cent) of the crops and 7 (9 per cent) 
of the gizzards. Lantana is abundant in zone 
B, common in Ci, and occasional in A and Di, 
and this distribution makes it widely avail- 
able throughout dove range. However, its rela- 
tively infrequent occurrence and small volume 
in the diet implies that it is not a generally 
preferred food. Almost the entire volume of 
this plant in the food analysis came from four 
Lace-necked Doves taken at Koloa, Kauai, 
in zone Ci. Two Barred Doves collected at 
the same place and time had also eaten large 
quantities of Lantana although it was not a 
common food of Barred Doves. Possibly the 
Lantana here was particularly attractive at 
this time or other foods may have been lack-
