They can be useful for modeling species-habitat associations, documenting species distributions, and any other presence-only data applications. Field activities included surveys for one or more of the MSHCP's covered species and vegetation monitoring for the purpose of assessing community change or for assessing habitat for covered species. However, data in this dataset represent observations made within the boundaries of the Conservation Area as it existed in A buffer of 30 meters around Conservation Area boundaries is allowed to account for error in GPS coordinates recorded in the field.

This dataset is intended for distribution to the general public, researchers, government, and commercial users as documentation of species presence at a specific place and time. These data may be useful for modeling species-habitat associations, documenting species distributions, and any other presence-only data applications. Access Constraints: These data are available to members of the general public, researchers, government, and commercial users.

No portion of this dataset, nor any prior dataset released by the Biological Monitoring Program, should be redistributed without prior written approval from the Biological Monitoring Program or the Western Riverside County Regional Conservation Authority.

Extent West Scale Range Maximum zoomed in , Minimum zoomed out ,, Summary These data document locations of species at specific places and times. Description Each record represents an observation of a specific species at a given location on a given date and time.

First, we soon lost contact with some tagged birds, suggesting that they continued to migrate north out of the Plan Area. Second, most of the tagged birds appeared to be non-breeding birds based on beak color and lack of characteristic red skin coloration and warts on their face.

Third, our tagged birds were very difficult to follow due to the great distances that TUVU cover and the uneven terrain over which they travel. Finally, the tagged birds soared over and roosted within areas that are not in conservation and therefore were inaccessible to us.

The hills have suitable caves and ledges, permitting vultures to nest relatively undisturbed. In addition, the Bernasconi Hills border good foraging habitat and the nearby trees and lake provide good roosting sites and an additional food source. We were not successful in finding TUVU nests in other potential nest sites in the Plan Area, but budget limitations restricted the time we could spend in these areas.

It is possible that with additional search effort, new nest sites can be discovered in these areas. Recommendations for Future Surveys We recommend tagging only TUVU that are of apparent adult breeding condition to improve the chance of following a bird to an active nest site.

We also recommend starting the trapping process at least 2—3 wks later to avoid capturing northerly migrating TUVU. Also, there may be a greater chance of trapping adult breeding birds later in the season because parents must intensify foraging for food as chicks age. More intensive survey efforts should be directed at Rawson Canyon to determine if that area is occupied by nesting vultures.

Finally, birds captured in should be relocated to determine if these birds regularly return to the Plan Area during the breeding season and potentially breed here. Batteries in the transmitters will likely last long enough to track birds during the spring and summer of , and possibly even into Eagles, hawks and falcons of the world.
