Last Month in Birding: October 2015

Every month we feature a few the past month’s bird sightings as suggested by our experts. Here are five notable observations from October.

Purple Gallinule (Porphyrio martinicus)

A living rainbow, this bird has enormous feet that enable it to walk across floating wetland plants such as lily pads. It can also swim. The purple gallinule is essentially a tropical species, and in the US it is typically found only in the far south and southeast. However, individuals regularly wander and turn up in odd places during migration—such as this one found at the Westborough WMA in Worcester County.

Bell’s Vireo (Vireo bellii)

Another southern species, the Bell’s vireo breeds in the central and western US and parts of Mexico, and winters in Mexico. A small, fairly plain-looking songbird, it has a remarkably loud song. Researchers at the Manomet Center for Conservation Sciences banded a Bell’s vireo last month. It was the third such occurrence since 2005.

Rufous Hummingbird (Selasphorus rufus)

Native to the western US, the rufous hummingbird breeds as far north as Alaska. It is a speedy, vibrant species, and makes up for its small size with tenacity and aggression. The male’s throat is orange but the female only shows a spot of orange. Last month a rufous hummingbird was seen in Great Barrington. The Allen’s hummingbird, a very similar species, can be very hard to distinguish from the rufous. Fortunately, the bird in Great Barrington was an adult male with a distinctive, completely rufous-colored back.

Say’s Phoebe (Sayornis saya)

Last month we shared a report of a Say’s phoebe on Nantucket. In October, another individual was spotted in Eastham. This western flycatcher is at home on ranches, and in badlands, desert edges, and other open arid habitats. It breeds all the way to northern Alaska and winters in parts of the southwestern US and Mexico. Individuals sometimes wander East during fall migration, and when they do, they inevitably make an eastern birder’s day.

Northern Wheatear (Oenanthe oenanthe)

This songbird is master traveler. It nests in Europe and Asia—with some birds entering North America in the high north from both the east and west—and winters in sub-Saharan Africa. Researchers have found that Alaskan northern wheatears travel an average of over 9000 miles to reach their wintering grounds! Stragglers sometimes find their way south to Massachusetts, where one was spotted at the Wachusett Reservoir in Worcester County last month.

Bats: Legions of the Night

As Halloween approaches, bat-themed decorations swarm store windows and homes, often in the company of black cats and other creatures synonymous with mystery and dread. Though bats have become symbolic of our spookiest holiday, they are benevolent, diverse, and fascinating throughout the year.

One out of every five mammal species on earth is a bat. They may look like flying mice, but bats are more closely related to the carnivores and hoofed animals. They are the only mammals capable of true flight, and their wings consist of four elongated fingers with skin stretched between them.

Nine species live in Massachusetts. All eat insects and hunt mainly from dusk to dawn. To find prey in low light, they make high-pitched sounds that bounce off their surroundings and return to their ears. By analyzing the way these sounds echo off of insects, they can discover their target’s size, location, and direction of travel. A single bat can eat 600 moths and other insects in an hour.

Since prey is scarce in the winter, Massachusetts bats migrate south or hibernate. Five species overwinter in cold wet caves. In recent years these habitats have hosted a fungus—probably introduced from Europe—that causes a deadly illness called white-nose syndrome. As a result, these five cave-dwelling bats are listed as endangered in Massachusetts.

Scientists have successfully treated some bats for the disease. But there’s much more work to do. Help protect bats by making sure that you don’t disturb their summer and winter roosts. Also, support the conservation of natural areas that keep insect populations in balance, allowing bats to continue flying our skies during the witching hour and beyond.
