Final answer:
The annual trend in turkey vulture sightings along the survey route shows a peak in spring and summer and a decline in winter and fall.
Step-by-step explanation:
The annual trend in turkey vulture sightings along the survey route can be described as follows:
- In the winter months, turkey vulture sightings are typically low. This is because many turkey vultures migrate to warmer climates during the colder months.
- In the spring and summer, the number of turkey vulture sightings increases. This is because they return from their winter migration and are active in their breeding and nesting activities.
- In the fall, turkey vulture sightings may again decrease as they prepare for their migration to warmer climates for the winter.
Overall, the trend shows a peak in turkey vulture sightings during the spring and summer months and a decline in the winter and fall.
