padding:0cm 5.4pt 0cm 5.4pt;height:15. What is a "heartnut" tree?

I had mixed warbler feeding groups in these trees each day roughly July 29-Aug 4. I have eBird reports in for those two dates that include all of your top 7 species, plus Black-throated Green and Nashville. I felt the majority of these birds, more than half juveniles, were migrants, altho several also nest locally. I felt they were migrants because they were all there together, especially each morning. > Rick Whitman > > On 8 August 2016 at 12:20, John Kearney <john.kearney@ns.sympatico.ca> wrote: > Hi All, > > The rate of nocturnal movements of warblers at Carleton, Yarmouth County, almost doubled over the previous week. There was a total of 240 calls and at least 181 individual birds at a rate of 34 calls per night. Warblers composed 99% of the calls recorded. Despite a continuing variety in species composition, early migrating warbler species dominated the count. The most common species were American Redstart (69 calls), Black-and-White Warbler (45 calls), and Yellow Warbler (34 calls). The numbers of these three species seemed to indicate true, south-bound migration, rather than post-breeding dispersion. A summary list can be found below. > > The weather radars in the state of Maine, at Caribou and Portland, showed only light activity but with evidence of bird migration on most nights when there was no rain.
