Canada (Gray) Jays: Question 20 options: cache (store) thousands of edible items through the summer and fall have enlarged salivary glands that are used to wrap food in a saliva blanket have an excellent spatial memory for finding stored food nest early early (often by early March), long before most other birds start nesting all of the above

Synthesis/Evaluation SYNTHESIZE YOUR KNOWLEDGE Acorn woodpeckers (Melanerpes formicivorus) stash acorns in storage holes they drill in trees. When these woodpeckers breed, the offspring from previous years often help with parental duties. Activities of these nonbreeding helpers include incubating eggs and defending stashed acorns. Propose some questions about the proximate and ultimate causation of these behaviors that a behavioral biologist could ask.
Clark's nutcracker is a bird species that often performs better in spatial memory tasks compared to other species of closely related birds. What is the proposed evolutionary explanation for this phenomenon? a. Clark's nutcracker has an overall larger brain than the other species after controlling for body size. b) Clark's nutcracker caches nuts and other food in to certain spaces in the environment, and selection has led to an improved spatial memory in this species so as to help it remember where it stored food. c) Clark's nutcrackers maintain smaller territories and therefore it is easier for them to remember items compared to the other species. d) The other species did not comprehend the spatial memory challenge.
