Watching Warblers
by Michael Male and Judy Fieth
Blue Earth Films, 1996
60 Minutes, VHS Videotape
Fire up your VCR and sit back, because you're in for a treat with this video of the warblers of
eastern North America. The introduction whets your appetite with brief snips of several
species, images so close that you can see feathers on the throat vibrate as each male belts out
his song. Images gets closer and closer, until you can actually see the tongue of a Swainson's
Warbler as he exchanges songs with a rival male. There is no human voice for several minutes,
when there is a brief introduction to the tape.
Treatment of individual species is organized by geographic distribution and nesting habitat,
and the narrative focuses on behavior and breeding strategy. A typical species account
includes a panorama of preferred habitat, with a description of the bird's behavior. For
example, the ovenbird "spends most of the time on the ground, not hopping like most
warblers, but walking." For the beginning birder, this can be invaluable information as they
learn how to look for different species. This behavior information is followed by superb
images of a singing male, although coverage of the females is a bit weak. Many species
accounts include intimate images of nests and young. The birds show no signs of discomfort,
so it must be assumed that the authors were exceptionally careful in setting up blinds to avoid
disturbance.
The voiceovers are done by the authors, who describe breeding habitat, nest construction, and
behavior. These narratives are fairly brief, but nonetheless provide good information, and the
authors allow many moments of uninterrupted footage of these birds moving about and
singing.
There is a brief discussion of fall migration, with a handful of images of these migrants. If I
were pressed to find fault, I would have wished for a fuller treatment of the fall plumages.
From the point of view of field identification, these are obviously the most problematic. This
is followed by a discussion by the authors about the threats posed to warblers by human actions,
such as destruction of habitat, and the creation of conditions favorable to predators. While
somewhat preachy, it is clear that the authors feel passionately, and if the watcher is not aware
of these threats, it is useful instruction.
The tape finishes off with snippets of each singing male, with the species printed over the
image. To my ear, this appears to be loosely organized by the similarity of the songs. This is
a handy warbler review, just the thing for a quick preparation for a field trip.
The quality of both video and audio is exceptional, and highlights are many. A male Chat in
courtship display with full audio, is followed by a close-up showing him singing his bizarre
song, throat throbbing with enthusiasm. A Blue-winged Warbler struggles to feed a nestling
an oversized insect pupa, as its mate leans in now and again to help. When it is finally
successful, it picks up a fecal sac and flies off.
The authors have truly captured the magic of these little avian jewels, and this video will
undoubtedly be treasured by anyone who watches it. There is nothing like watching a bird
singing to learn its song, and this video will be a first-rate learning tool for beginning and
intermediate birders. For the experienced birder, it is simply a joy to watch.
