I've only seen a few warblers in the backyard. Even then, those few were likely attracted
to the insect richness found within a dense row of cedars. I have also seen a BT Blue in
those cedars, but only once, a few years ago. If I am lucky enough to spot a warbler it
tends to be a Magnolia warbler. Once I spotted two of them at the same time. Both Magnolia
warblers and Common Yellowthroat can often be located closer to the ground, low in a bush,
and sometimes nearly oblivious to a relatively motionless photographer in their midst. Like
most warblers, and many other birds, both these species move through bushes in a particular
direction and therefore you can move ahead of them and then remain motionless and wait for
the warbler(s) to come to you. I've noted that this simple technique does not seem to work with
Brown Creepers because they seem to confound any strategy you might feel inclined to execute.
You should have no trouble spotting a male CYT in the spring if you visit a migratory hot spot
where birds are funneled through a bottleneck like a spit.
