Question

a group of researchers gathered data on the number of cliff swallow road kills they observed while driving between nest sites in nebraska. the data cover a period of about 30 years and date back to the time when cliff swallows first started to nest under highway overpasses.

Answer 1

This question is about studying the impact of highway overpasses on cliff swallows.

Step-by-step explanation:

This question falls under the subject of Biology in High School. The researchers in this study collected data on the number of cliff swallow road kills observed while driving between nest sites in Nebraska. They were studying the impact of highway overpasses on cliff swallows nesting behavior and survival.

Answer 2

The question concerns the field of Biology, with a focus on ornithology and ecology, involving the study of cliff swallow road kills and bird migration. The data assists in understanding species decline and conservation efforts. Tagging and tracking help reveal migration patterns and bird behavior.

Step-by-step explanation:

The student's question relates to the field of Biology, specifically ornithology and ecology. The research mentioned involves gathering data on cliff swallow road kills and studying bird migration patterns and nesting habits. Such research can be used to determine the impacts of environmental change, migration routes, and species decline. With regards to the cliff swallows, the data gathered over a 30-year period in Nebraska can help understand the impact of human infrastructure on wildlife. Information on nesting site protection and the tagging of birds to study sparrows and Swainson's hawks migration routes are good examples of conservation biology practices and understanding avian behavior.

To conduct a study on whether birds of various species recognize the predator warning calls of other species, a biologist might use a series of feeders and audio equipment to play different calls and observe the reactions of feeding birds. The schema has shown success in protecting nests, which is a positive outcome for species conservation and population studies.
