Q

what was done to see if honeyguides associated vocal signal with higher payoff? and what was found?

Q

if the honey hunting call brr hm was used then what % probability was there for eliciting guide from the honeyguide?

A

66.7%

17
Q

when the control sounds were produced what would the honeyguides do?

A

stop guiding behaviour

18
Q

what were the % of bees nests found for each:

a) honey hunting specialised sound
b) human control
c) animal control

A

a) 81%
b) 67%
c) 50%

19
Q

what did using the honey hunting sound do to the chance of finding a bees nest?

A

more than tripled it

20
Q

what has the interaction likely evolved by?

A

NS

21
Q

what does the study show that a wild animal is capable of doing?

A

attaching meaning and responding to a human signal of recruitment for cooperative foraging

22
Q

learning may occur socially from other birds near bees nests, what does this result in?

A

a tradition in the honeyguides that reflects customs of the human honey hunters

23
Q
