General comments can be sent to either of the California Partners
in Flight Co-chairs: Geoff Geupel or Deborah Schlafmann, or California
Partners in Flight Coordinator Kim Kreitinger. Comments relating
to technical aspects of mapping or website should be directed to
Grant Ballard. For comments on specific plans or to contribute data
relating to specific plans, please refer to to those areas of this
- Information used for each species to develop conservation plans:
- Maps or information on historical distribution and abundance
- Maps of current distribution and information on current breeding
status, density and health throughout California, wherever information
is available. Maps should show distribution by the bioregions
established by the California Biodiversity Council. These bioregions
correspond to the Riparian Habitat Joint Venture's Regional
Breeding status will be ranked on the following scale:
- 0 = No evidence of breeding: Species not detected during
breeding season, or captured only on migration (with high fat
- 1 = Confirmed breeding: distraction display; nest building
(except woodpeckers and wrens); nesting material or fecal sack
being carried by adult; captured female with eggs in oviduct;
dependent juveniles with adults; juvenile with no skull ossification
before 1 August; active territory observed on at least three
days of spot mapping (at least a week apart), active nest observed.
- 2 = Possible breeding: Species encountered singing or
acting territorial only once during the breeding season (in
- 3 = Probable breeding: Singing individual encountered
on 2 or more different days of standardized censues (at least
one week apart); territorial behavior noted more than once at
the same location; pair observed in courtship behavior; female
with brood patch (males with cloacal protuberances not used
as evidence of breeding locally).
Information regarding breeding status should be based on one
or more of the following (specify): Expert opinion , Point count,
Mist netting, Nest searching, Spot mapping, Area search, Breeding
Bird Atlas, BBS route, or Other/Local opinion.

Disclaimer: these maps are not comprehensive and
are not intended for use as definitive range maps. In particular,
study areas do not necessarily match a given species' range, so
red dots do not necessarily mean that a species should breed at
a given location. Further, several data sources exist which are
not represented here. We encourage users interested in species distributions
to consult a wide range of references, including (but not limited
to) the Birds of North America series, county breeding bird atlases,
and the California Natural Diversity Database.
