Earth Matters : Eastern screech-owls: Why there and not here?

by David Spector

Naturalists are often asked “W” questions: What is this organism? Where is it found? When am I likely to see it? And, most interesting and most difficult to answer, why? Why-questions provoke answers that address natural processes, often multiple, complicated, and incompletely understood processes. Full answers to why-questions include acknowledgment of uncertainty.

In the News Living Building Project : Feather-friendly: Hitchcock Center partners with Fish & Wildlife to reduce deadly avian impacts at building

By Scott Merzbach

Life-threatening dangers are posed any time a migratory bird approaches a building, unaware that it could be on course to strike a window. “They just see a reflection of vegetation or of the sky,” says Randy Dettmers, migratory bird biologist at U.S. Fish & Wildlife Service in Hadley, who estimates that 20 to 30 birds annually can be fatally injured at any one- or two-story building.

Earth Matters : Spotting rare birds among the common: Birdwatching tactics for observing abnormal bird behavior

Birdwatchers make lists. We list bird species seen by day, week, year, or lifetime. We list birds seen in a yard, town, state, or continent. We compete and get a special thrill from finding a stray from far away.

Earth Matters : From Big Sits to Birdathons: Birding competitions far and near

By Joshua Rose

A few months ago, headlines flared that Peter Kaestner had seen his 10,000th bird species. This could have been anticlimactic, as Kaestner has been renowned for years among birders for traveling worldwide and seeing more species than anyone.

However, the feat gained drama just before Kaestner’s milestone when Jason Mann, so non-renowned that few birders had ever heard of him, suddenly revealed that he, too, was approaching 10,000 species seen, and even claimed to have reached the milestone mere hours before Kaestner did. Mann ultimately was found to have padded his list a bit and withdrew his claim, but for a while, the title of world’s top birder unexpectedly became a competition.

Earth Matters : How much of natural history is lost in translation?

By Meghadeepa Maity

In a past column, I wrote of “a Bengali poem that I‘ve loved forever” which references several species of wildlife and plants, and “stands out for the unsaid depth of emotion — it speaks of nostalgia, grief and homesickness.” আবার আসি ব ফি রে (“Abar Ashibo Phirey”) was written in 1934 by Jibanananda Das (he/him) and published posthumously in 1957. I’d recited the poem at a bird walk once, and after requests from several attendees, I determined that a translation was necessary.

Earth Matters : Brood parasites are more innovative survivors than evildoers

By Joshua Rose

Maybe you looked into a bird’s nest and saw one egg that was a different size and color than the rest. Or you noticed a chick that was larger, louder, and more aggressive than the others. Maybe you saw a parent bird feeding a chick larger than itself, and different in color and shape. What you saw was a brood parasite, an animal that fools animals of other species into caring for its offspring, usually at the expense of the host species’ own young.

Earth Matters : How farmlands can support wildlife, not just people

By Lee Halasz and Kari Blood

This winter has been one of the warmest on record in Massachusetts, and around the nation, extreme weather events are in the headlines on a regular basis. Scientists agree that our rapidly warming planet is now feeling the effects of the climate crisis. However, climate change is not the only crisis our planet faces. For decades, scientists and conservation groups have also been raising the alarm about the “biodiversity crisis,” in which wildlife populations are plummeting. Fortunately, one solution to addressing these challenges may lie in a surprising place: the farmlands that help define the landscape of the Connecticut River Valley.

Earth Matters : Bird joy as resistance in a troubled world

By Meghadeepa Maity

When I look at the news, I’m far more likely to see a Black victim of police brutality than to see a Black birder like Dexter Patterson (a.k.a. The Wisco Birder) singing and laughing in the woods. Today’s mainstream media have shown a necessary, heightened presence of minorities, but it’s a far cry from the kind of visibility we need. The disabled, queer/trans folks, BIPOC (Black, Indigenous and other people of color), immigrants and the poor are so often and so exclusively represented in our suffering, that after the latest targeted mass shooting has gone off air, we can just cease to exist in the public memory. We deserve to be recognized and amplified in our everyday joy, dignity and successes, rather than only in light of a catastrophe.

Earth Matters : Why do animals communicate?

By David Spector

For many years my research brought me outside in May and June about an hour before sunrise to hear and record yellow warblers. Males in breeding season sang intensively for a half-hour or so, and, depending on their mating status, sang in a somewhat different style and less intensively well into the morning. Females often responded to male song with “chip” notes, and both sexes used a variety of short calls. Each vocalizing bird revealed its location, and often much more information — its species, its sex, its individual identity, its mating status, its willingness to fight if approached by another of the same species and sex, and perhaps more about its behavioral state. Such information is valuable, possibly affecting the bird’s survival. Why share it? How might sharing this information benefit the individual animal? I suggest three answers to these questions: leakage, manipulation and probing.

Earth Matters : Inclusivity becomes reality at a Maine camp

By Meghadeepa Maity

This is a story about how one organization’s exemplary commitment to inclusivity helped me realize a dream. I’m a queer, disabled, South Asian immigrant, an avid birder and an activist in the North American birding community. For as long as I can remember, I have wanted to see an Atlantic puffin. It’s often easier for organizations to publish a statement rejecting marginalization in the wake of racial reckonings, than it is to take concrete steps to welcome those of us who have historically been excluded from outdoor recreation and conservation. But the National Audubon Society followed through, and I was a beneficiary.

I first proposed camperships for BIPOC (Black, Indigenous and other People of Color) youth as an action item on a local inclusion committee two years ago. This summer, I was incidentally awarded a fully funded Audubon BIPOC scholarship that led to a transformational experience at the weeklong “Puffin Islands” camp at Hog Island, Maine…
