Collecting Data

The article collected data about

• rate at which predators attacked the differently-coloured bird models

• 3D-printed fairy-wren models

• colourful plumage

• chances of survival

The article explains that data showed that

• Each model was attacked roughly the same number of times.

• 2,511 model fairy-wrens, 331 showed signs of an attack, an attack rate of 13.2

• The attack rate was similar for both conspicuously-coloured models and dull brown coloured models.

• All of the above.

What equipment was used to collect this data?

• Cameras

• Bluetooth bird trackers

• Drones

• None of the above

The cacophony project recorded sound

• at regularly timed intervals

• in inaccesible locations

• during the night

• using infrared cameras

Data showed that what percentage of the wild brown kiwi spent time foraging?

• 100%

• 60%

• 88%

• 96%

What equipment did scientists use to study the behaviour of the brown kiwi?

• Infrared cameras

• Cacophonometer

• Heart rate monitors

• Ethogram

What data did scientists collect to determine whether zebra finches recognise sounds from before they are hatched?

• comparing heart rate of birds when exposed to bird calls or silence

• comparing gene expression of areas associated with auditory processing

• comparing the behaviour of birds once hatched using an ethogram

• none of the anove

The diagram shows an example of an

• ethogram

• histogram

• binomial distribution

• activity gram

Why does Aroha discard data with noises other than birds present?

• She is managing the controlled variables.

• This ensures that the data she collects is only representative of the birds.

• Other noises would unfairly represent the volume of the birds.

• All of the above.
