Comparison of Florida Scrub-Jay Juvenile Production in Different Landscapes

. Justification and Background. The Florida Scrub-Jay is the only endemic bird to the state of Florida and is threatened with extinction. Their habitat is becoming fragmented and degraded making it hard to have nest success.Two study sites were selected because of the difference in habitat.The optimal habitat is dry oak scrub measuring between 120cm and 170cm with open sandy areas. This habitat is controlled by natural and prescribed fires..

    3. Methods Peanuts were used to bring the birds in close enough to see the bands on the legs. Juveniles were selected to count because they are a measure of overall demographic success. Counting juveniles measures the success of each breeding pair and gives an estimated number of birds that will be breeding in the upcoming years. The number of juveniles from each study site are compared to see if they are significantly different. Significance was determined using the Mann-Whitney Test.

    4. Related Reading Tel-4 (T4) produced more juveniles per breeding pair than Happy Creek (HC). T4 averaged 0.929 juveniles and HC only averaged 0.231. The habitat at T4 had more openings possibly helping the birds to spot predators more effectively.
