Spring migration has begun in earnest and we are at the height of warblers arriving in and passing through New England. These little jewels, especially the colorful males, are a sight to behold as they flit about in shrubs and trees, constantly gleaning insects amongst the branches, flowers and emerging leaves. Getting and keeping a warbler in your binoculars can be challenging, to say the least — these busy little birds give the Energizer Bunny a run for its money.
As to when to look for warblers, the best times (“fallouts”) are when there’s a south wind (saves birds flying north considerable energy) and a change in the weather, such as a storm. The birds are forced to seek land, which is where we find large concentrations referred to as “waves” feeding furiously to fuel the rest of their journey.
The pictured Yellow Warbler, weighing 1/3rd – 1/4th of an ounce, left its wintering ground in Central or South America and travelled perhaps as far as 4,000 miles or more in order to return to Vermont this spring.
