Resumen:
Animal transport is an indispensable
practice in species that need to be moved for management
or commercial purposes. However, transport may
have negative effects on individuals welfare. The aims
of the present work were to determine if the behavioral
responses of adult Greater Rheas (Rhea americana)
bred in captivity are sensitive to short-term transport
and if males and females differ in their posttransport
behavioral activity and recovery. Eight males and 8 females
were placed in individual pens and allowed 6 d
to habituate (d 1 to 6) before transport procedure. On
the transport day (d 7), half of the birds (4 males and
4 females) were randomly assigned to a transport group
that was captured and handled to be placed into the
crates, exposed to a 30-min transport stressor, and immediately
returned to their pens. Four transports with
1 different male and female each time were performed.
The other half remained undisturbed and were used as
controls. Behavior of all individuals was video-recorded
during habituation days, after transport on d 7, and
on the 2 following days (d 8 and 9) to evaluate preand
posttransport behavioral activity for 2 h per day.
No significant behavioral changes were observed during
the last 2 d of the habituation period (d 5 and 6), suggesting
that Greater Rheas were adapted to the housing
conditions before transport. After transportation,
several behaviors were affected: transported males and
females showed null resting, transported females also
showed reduced preening and increased vigilance (P
