watching and enjoying the hummingbirds, please fill out
see in your yard, using the Abundance
form. Collecting abundance
an essential part of the project.
& Abundance data
you may also report information on the behavior of the hummingbirds.
If you chose to collect behavioral data, use the Behavior & Abundance
form instead of the above form.
This will be extremely valuable in understanding the abundance
data and species interactions taking place among hummingbirds.
for behavior data collection
request that you fill in information regarding the following
A bird is feeding from a feeder, or flower, with a few second
break between feeding bouts.
If you report the bird
is feeding, please add the feeder / plant information in the
next two columns.
sitting on a branch / feeder and such, in an erect posture, usually
The bird is perched and singing. Posture is either erect or with
flight and/or Insect
Bird flies to a point in the vicinity of the feeding place, then it hovers
for a few seconds in place,
then flies to a second
point and hovers, and
forth. The bird may be feeding on insects
in the air (although they may be too small for youto see them).
flight includes climbs and dives (up to ~40 meters high) above
object (another hummingbird / other bird species/ predator /
human). 5-10 dive displays may be given in a sequence. Flight
may or may not include vocalization.
Chasing: A hummingbird
pursues another individual and chases it out of the area. This
pursuit usually occurs by a displayer.
you report the bird is chasing or displaying, please add in the
information about the species that is being chased, or the target
of the display (if known).
you have collected the data, please report
this web site.
enter your data on a weekly basis. This will enable us to follow
changes in hummingbird'
responses as they occur. It will also prevent large amounts of
data accumulating and hours of work in a later stage. Please
save all your data sheets and send
them to us* at the end
of the project as a backup.
