Evaluating Response at Management Site
Until a centrally coordinated monitoring system is
in place, we recommend that biologists working
with land managers address the following
question:
Are Golden-winged Warblers present and if so,
is there a breeding population?
Research has shown that documenting the
presence of territorial males alone does not
indicate a breeding population. Additional
evidence must be gathered before you can be
confident that males are acquiring mates and
actually breeding. The following are two methods
to help you document these two responses to
management:
1. Follow the field protocol described in
Appendix F to determine if Golden-winged
Warblers are present.
2. If Golden-winged Warblers are located onsite,
then attempt to confirm breeding
activity. Probable breeding activity includes
one of the following: Presence of a female
Golden-winged Warbler or presence of at
least 4 territorial males within singing
distance of one another. Confirmed breeding
activity includes observation of one of the
Evaluating Progress toward Conservation Objectives
The two goals of this plan can only be realized by

specific metrics and targets for evaluating success

and related objectives (Table 3–16).
