Studying Juncos: Key Concepts

Mr. Nolan introduces the study of model organisms, focusing on juncos to understand population changes. He describes the characteristics of juncos found in Michigan and California, and instructs students to watch a video for further insights. The video highlights differences between junco populations at UCSD and Mount Laguna. Pamela Yeh's research on these birds is discussed, and students are encouraged to analyze data and answer questions about the populations' breeding habits and environmental interactions.

What is the primary focus of the study involving juncos?

• To analyze their diet

• To study population changes

• To observe their mating rituals

• To understand their migration patterns

Which subspecies of juncos is found in Michigan?

• Dark-eyed junco

• Yellow-eyed junco

• Slate-colored junco

• Oregon junco

What is a notable feature of the juncos found in California?

• They have a bright yellow beak

• Their backs are more brown

• They have blue feathers

• They are larger in size

Why is the UCSD campus a convenient location for studying juncos?

• It is isolated from other environments

• It has a large population of juncos

• It has a unique climate

• It provides easy access for researchers

What is a key difference between the UCSD juncos and the mountain juncos?

• UCSD juncos stay on campus year-round

• Mountain juncos have a longer breeding season

• Mountain juncos are larger in size

• UCSD juncos migrate seasonally

Who is Pamela Yeh in the context of the junco study?

• A scientist studying bird migration

• A graduate student researching juncos

• A professor at UCSD

• A birdwatcher documenting junco behavior

What year did the juncos first appear on the UCSD campus?

• 1993

• 2003

• 1983

• 1973

What is one of the data sources mentioned for analyzing junco populations?

• Breeding season data

• Dietary habits

• Migration patterns

• Satellite imagery

What is a potential challenge in using juncos as research subjects?

• Their small population size

• Their unpredictable migration

• Their varied breeding habits

• Their limited habitat range

What should students consider when forming an argument about juncos as research organisms?

• The differences in their breeding seasons

• The climate of their habitat

• The color of their feathers

• Their diet and feeding habits
