Behle 1936 H.C. MVZ Berkeley, Calif. Nov. 20, 1936 Mr Egbert Jones of Ceres, Stanislaus Co., Calf. brought into the museum this morning two hybrid ducks bred in captivity which had been killed about October 10, 1936 by dogs. The two ducks have remained in cold storage since then. These preserved as study skins with my field numbers. 1092 ♂ Gadwall x Mallard B.S.Band No. 34-546851 wt. 839.5 1093 ♂ " " " " " " 34-618591 wt. 745.5 Data concerning these is as follows: In 1935 Mr Jones bred a wild ♂ Gadwall with a ♀ domestic mallard of small size coming from a strain known as "English caller". As a result of this union or rather following it the female laid a clutch of 90/10 eggs, only one of which was fertile. From this fertile egg a female hybrid was raised. In the following year, 1936, Mr Jones bred this hybrid ♀ to a ♂ domestic mallard. In the clutch of eggs laid by this hybrid female, all were fertile but only one ♂ was raised to maturity. This one was banded with B.S. band no 34-618591 and is one of those killed and now in MVZ (no. 1093 W.H.B). Also in 1936 Mr Jones again bred the original pair, the wild ♂ Gadwall
