Mourning Warbler
Sean is excited that some of our neotropical migrants are being seen more and more frequently here in the Northeast, and he hopes that we will all have the chance to see some uncommon species like this Mourning Warbler (Geothlypis philadelphia) this weekend. Good luck, everyone!

The Kentucky Warbler (Geothlypis formosa) is one of the more common neotropical migrants found in Cocobolo Nature Preserve. They can be found in a mixture of habitat types, but seem to prefer mature secondary growth. Our crew has even caught an individual in the same net on the same day two years apart, showing the incredible site fidelity some of these birds possess.

Read MoreThe Four MoSI Warblers
The 2014-15 MoSI, or Monitoreo de Sobrevivencia Invernal (Monitoring of Winter Survivorship), protocol banding season for the Nicoya Peninsula Avian Research Station is now in the books. Here we have four species, in the form of Neotropical migratory warblers, that were banded and recaptured over the years at the station: the Tennessee Warbler (Oreothlypis peregrina), Black-and-white Warbler (Mniotilta varia), Prothonotary Warbler (Protonotaria citrea), and Northern Waterthrush (Parkesia noveboracen). Banding research is critical to gain an understanding of where and why they return to...

One of the most spectacular warblers in the world is the Blackburnian Warbler (Setophaga fusca). They are truly gorgeous little creatures and thankfully here in the Chautauqua-Allegheny region they are abundant in migration and nesting seasons. I have been delighted to see and hear so many of them in the past month, and I am looking forward to spotting them in our neighborhoods, yards, parks, state forests and other preserves until the fall. Twan had this individual in Allegany State Park earlier this month. They are fireballs flitting around our forests in their bright spring colors. Here...
Read MoreChestnut-sided Warbler close-ups
Today while conducting field work for several hours at a few sites in Pennsylvania I enjoyed numerous great looks at Chestnut-sided Warblers. These birds of shrub/scrub habitat and secondary growth are distinctive and beautiful in appearance and song. Whenever I see them now I am reminded of Twan and Sean and RTPI’s work in the tropics. In Costa Rica in the Chestnut-sided wintering range they enjoy watching the birds turn into little “meatballs” as they fatten up for the flight north. In fact a Chestnut-sided Warbler banded in Rara Avis was recaptured twice over a four year...
