California Department of Fish and Wildlife (CDFW) 20190905 vector digital data https://www.wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/2900_2999/ds2937.zip The Bald Eagle Observations Database is a product of the California Department of Fish and Wildlife's (CDFW's) Wildlife Branch and Biogeographic Data Branch. The records generally represent bald eagles (BAEA, Haliaeetus leucocephalus) nesting, perching, and flying. Additional information about the eagle, the database, and submitting data can be found on CDFW's Bald Eagles in California Webpage: https://www.wildlife.ca.gov/Conservation/Birds/Bald-Eagle. This dataset represents observed nest locations for Bald Eagles, generalized to a 2.5 mile hexagon grid. If you need more specific location information, please contact the listed point of contact in the metadata. This is a spatial database compiling multiple sources of bald eagle observations into a standard format for comparison and management. The observations contained in this dataset may not be represented in the California Natural Diversity Database (CNDDB) but may be included in the future. For the time being, users should utilize both datasets concurrently.

Nest The record represents a bald eagle nest site Fly-over The record represents a bald eagle that was primarily observed flying Perched The record represents a bald eagle that was primarily observed perched Use area centroid The record represents the centroid of an area known to be used by a bald eagle or bald eagles. Area may represent a territory, home range, feeding area, or any other area of observed use. Unknown The record type is unknown SurveyType The survey method used to detect the bald eagle(s) or nest. (aerial, ground, incidental). Aerial survey conducted by aircraft, helicopter or fixed wing Ground survey conducted from traversing the ground Incidental An incidental, non-systematic detection of a bald eagle Unknown The survey method is unknown NumTotal Total number of bald eagles detected at represented point. A null value indicates that the number of birds detected is unknown. NumAdult Number of adults detected. An adult is an individual eagle capable of breeding, generally about 4-5 years of age; generally after fourth year or after fifth year (definitive basic plumage) Number of adults detected. An adult is an individual eagle capable of breeding, generally about 4-5 years of age; generally after fourth year or after fifth year (definitive basic plumage) NumSubAd Number of subadults detected. A subadult is an individual eagle greater than 1 year old, but typically not able to breed; generally second year to fourth year (basic I-basic III plumage) Bloom & Clark 2001, Driscoll 2010 NumJuv Number of juveniles detected. A juvenile is an individual eagle less than 1 year old; generally hatch year and early second year Bloom & Clark 2001, Driscoll 2010 NumFledgli Number of fledglings detected. A fledgling is an eaglet that has recently flown from the nest (See Driscoll 2010) or a young eagle that has taken the first flight from the nest but is not yet independent (See USFWS 2009). Driscoll 2010, USFWS 2009 NumNestli Number of nestlings detected. A nestling is an individual eagle between the time of hatching and the time it takes the first flight from the nest Bloom & Clark 2001, Driscoll 2010 NumEgg Number of eggs detected NumUnkAge Number of unknown age class eagles detected Behavior1 The primary activity or behavior of the observed eagle. Examples include, perch, fly, brood, feed, incubating, courtship display, territorial display, etc.). Behavior2 The secondary activity or behavior of the observed eagle. This may be an inferred behavior; e.g. a BAEA seen flying may be assumed to be hunting. Examples include, feeding, preening, hunting, resting, etc. NestOccup Description of the nest occupancy by eagle. (Occupied, Unoccupied, Unknown). A previously known eagle nest occupied by a different species would be considered unoccupied for the bald eagle database. Occupied A nest used for breeding in the current year by a bald eagle pair. Presence of an adult, eggs, or young, freshly molted feathers or plucked down, or current years’ mutes (whitewash) suggest site occupancy Pagel et al. 2010 Unoccupied Those nests not selected by bald eagles for use in the current nesting season. Nests would also be considered unoccupied for the non‐breeding period of the year Pagel et al. 2010 Unknown Unknown NestStatus Description of the nest status. (Active, Inactive, Tended, Successful, Failed, Unknown). Active A nest in which eggs have been laid (See Driscoll 2010) or a bald Eagle nest characterized by the presence of any adult, egg, or dependent young at the nest in the past 10 consecutive days immediately prior to, and including, at present Pagel et al. 2010 Inactive A bald Eagle nest that is not currently being used by eagles as determined by the continuing absence of any adult, egg, or dependent young at the nest for at least 10 consecutive days immediately prior to, and including, at present Pagel et al. 2010 Tended A nest with fresh mute (feces), fresh material, or signs of reconstruction within the year, but an egg or bald eagle was never observed Successful An active nest in which at least one young survived to an advanced stage of development (See Driscoll 2010), or Fledging success will be determined via the observation of young that are at least 51 days of age, or are known to have fledged from the observed nest (See Pagel et al. 2010) Driscoll 2010, Pagel et al. 2010 Failed An active nest in which the eggs did not hatch, or the young died before reaching an advanced stage of development (See Driscoll 2010), or nesting failure occurs when a nest where eggs were laid or where incubation behavior was observed fails to have any young reach 51 days of age (See Pagel et al. 2010) Driscoll 2010, Pagel et al. 2010 Unknown Unknown SiteID Unique site identifying code NestNum Nest Letter (A, B, C, etc) NestTotal Number of known nests in territory thoughout all years NestYear Year the observered nest was last used NestCond Description of the condition of the nest. (Intact, deteriorating, destroyed). Intact Nest integrity is well built and does not appear altered, dilapidated, or deteriorating Deteriorating Nest is not well built and appears to be falling apart Destroyed Nest material is completely absent or minimal remains, and nest substrate may be damaged or removed (e.g. felled tree, collapsed cliff ledge) NestSubst Description of the substrate the nest was built on. (cliff, outcrop, tree, utility, platform, other structure, other). Cliff A high steep face of rock Outcrop A rock formation appearing above the surface of the surrounding land Tree A plant having a permanently woody main stem or trunk, ordinarily growing to a considerable height, and usually developing branches at some distance from the ground Utility An electrical utility tower Platform An artificial platform to promote nesting Other structure Other man-made structure supporting the nest that is not a utility tower or platform Other Any other substrate not defined above; please describe in Notes field NestTreeSp Common or scientific name of the tree species if the nest was built in a tree. NestStage The stage of reproductive cycle the nest is in. (Build, lay, incubate, brood, branchers, fledged, nonbreeding, unknown). Build Adults are actively building a new nest or adding material/reconstructing an existing nest Lay Female is laying eggs; clutch incomplete Incubate A clutch of eggs are laid and are being incubated Brood Eggs have hatched and nestlings are being brooded Branchers (Also branchling) Young that are old and strong enough to leave the nest structure to nearby branches or ledges, but are not well developed enough to fly Fledged Young are capable of flight and have left the nest Nonbreeding Nest was observed outside of the breeding season Unknown Unknown SiteName The site name, territory name, project name, locality name, or other location reference (other than SiteID) used as a reference by observer. AltSiteName Name of the known alternate nest site for a particular territory. County County observtion is in. Notes General comment/note fields to explain any of the other fields or add additional information about the observation. ObsvrAffil Agency or organization affiliation of the observer/reporter. SourceID Unique ID given to a source. This the primary source. Use CNDDB source code when available.
