Question 1

paper:

Answer 1

bell miners provisioning calls are more similar among relative and ar used by helpers at the nest to bad their efforts towards kin

Question 2

bell miners interact with ___ in large colonies

Answer 2

kin and non kin

Question 3

Helpers of __ sex(es) work harder when provisioning the young of closer genetic relatedness

Answer 3

both sexes

Question 4

‘mew’ calls and genetic relationship trends

Answer 4

call similarity and increasing genetic relationship positing linear increase (esp between male helper and breeding male)

Question 5

individual mew call structure

Answer 5

inflexible and innate

Question 6

individual helping effort was more heavily influenced __

Answer 6

by similarity in call to breeding males than to genetic relatedness

Question 7

discrimination of kin from non kin via

Answer 7

olfactory, visual and.acoustic cues can occur

– acoustic common in birds they build templates

Question 8

template formation in complex societies

Answer 8

difficult, may create template to who they hear the most

-call may be genoptye dependent , reflect inherited differences in vocal tract morphology

Question 9

bell miners live in

Answer 9

highly social colonies several hundred

• helpers of both sexes
• nestlings have 8-10 helpers during nestling period (1-3 unrelated)

Question 10

mew calls stimulate

Answer 10

begging and increase prey transfer efficacy when they visit and leave

Question 11

_____ used to look at relatedness of cal

Answer 11

spectrographic cross-correlation (0 diff, 1 identical)

Question 12

no period of call learning was found?

Answer 12

innate? vocal tract morphology possible?

Question 13

mew calls similarity between the helper and the breeding male not female makes sense:

Answer 13

as majority of helpers are male and males have longer life span
