these recordings were collected

these recordings were collected passively by leaving a microphone in the

Maureen sent me these Rothfeld

Maureen sent me these Rothfeld recordings from nine colonies as

recordings from nine colonies as pictured these colonies span a distance

pictured these colonies span a distance

pictured these colonies span a distance of 260 miles on the Antarctic Peninsula

of 260 miles on the Antarctic Peninsula

of 260 miles on the Antarctic Peninsula I separated them into three different

I separated them into three different

I separated them into three different regions based on geographic location and

regions based on geographic location and

regions based on geographic location and now they had the recordings from across

now they had the recordings from across

now they had the recordings from across Antarctica in my possession I found that

Antarctica in my possession I found that

Antarctica in my possession I found that the field recordings sounded a bit

the field recordings sounded a bit

the field recordings sounded a bit hectic

[Applause]

[Applause] this is what penguin colony sound like

this is what penguin colony sound like

this is what penguin colony sound like all the Penguins calling at once it

all the Penguins calling at once it

all the Penguins calling at once it seems impossible to distinguish a single

single voice in any high school

single voice in any high school lunchroom I needed the clips to be a

lunchroom I needed the clips to be a

lunchroom I needed the clips to be a single calls so I could easily compare

single calls so I could easily compare

single calls so I could easily compare them and when you single in on one

them and when you single in on one

them and when you single in on one penguins call the vocalization sounds

penguins call the vocalization sounds

penguins call the vocalization sounds very unique music to your ears right now

very unique music to your ears right now

very unique music to your ears right now it was just a matter of comparing

it was just a matter of comparing

it was just a matter of comparing different clips like these at first I

different clips like these at first I

different clips like these at first I thought it would be as simple as telling

thought it would be as simple as telling

thought it would be as simple as telling the difference between someone from

the difference between someone from

the difference between someone from London and New York however the

London and New York however the

London and New York however the differences between these calls are so

differences between these calls are so

differences between these calls are so minut but they aren’t detectable by ear

minut but they aren’t detectable by ear

so instead I looked at the spectrogram

so instead I looked at the spectrogram or picture of these calls this is what a

I needed a customized computer program

I needed a customized computer program to ensure that the data I collected were

reliable and statistically valid and since there’s no app for that I set out

since there’s no app for that I set out

since there’s no app for that I set out to write my own program the only problem

to write my own program the only problem

to write my own program the only problem was that I didn’t know a single thing

was that I didn’t know a single thing

was that I didn’t know a single thing about coding I decided to take an online

about coding I decided to take an online

about coding I decided to take an online course on how to write code in a

later I used my new program to compare

later I used my new program to compare calls between colonies and between

calls between colonies and between

calls between colonies and between regions in order to determine if call

I found that regions farther apart have

I found that regions farther apart have more difference in their calls than

more difference in their calls than

more difference in their calls than those closer together

those closer together finally my big question was answered

finally my big question was answered

finally my big question was answered essentially I discovered that penguins

essentially I discovered that penguins in the three different regions have

make penguin calls together first let’s listen to that clip from earlier now

listen to that clip from earlier now

listen to that clip from earlier now everyone take a break from sitting
