![]() You’ll have lots of time to observe this common and agreeable species in coming weeks. In spring, however, birders celebrate the returning MYWA as their return signals migrants to come! We haven’t yet reached peak passage for this species but already MYWA have returned to our area in numbers, with another big push of birds present in the Navarre Marsh this morning. In fall, many birders lament the coming of MYWA as they indicate the impending end of migration and the beginning of cold weather. MYWA are almost always our first in and last out migrant warbler species and we have chosen to feature them on this, our last day of warbler species accounts for fall. As such, they are able to stay at higher latitudes than most other warbler species. This ability to adapt their food intake combined with their skill in using numerous foraging techniques, from ground foraging, to gleaning and hover-gleaning, to flycatching make them flexible and easy going, able to find food almost anywhere at any time. MYWA are also happy to dine on dogwood berries, poison ivy berries, and many other species of fruiting plants as well as insect prey which makes up the bulk of their diet outside of berry-season. In fact, the name “Myrtle” Warbler pays homage to their love of wax myrtle berries (Myrtica sp.) and MYWA even have special digestive adaptations that help them squeeze the most nutrition possible from wax berries. This warbler is quite hardy and due to its specialization in being able. The species name coronata from the Latin for wreath or crown refers to the bird’s yellow crown (Holloway). This species has a special affinity for fruiting trees, shrubs, and vines. The Yellow-rumped Warbler is now part of the genus Setophaga, moth eater, from the Greek setos, moth, referring to warblers in this genus that will hawk for insects. They are gregarious and vocal, and often flock together regularly giving contact call vocalizations to each other as they forage actively at all levels of the forest. The other is the Yellow-rumped Warbler (Myrtle), the more common of the two. ![]() These are the Yellow-rumped Warbler (Audubons), seen almost entirely in the western regions of North America, from northern Bristish Columbia into the southern ranges of the Rockies to the Mexican borders.
