Bird population fodder V (some good news finally)

After four days of hammering you with bad news, here are some good news graphics from the recently released bird population study that showed a decline of 2.9 billion birds, or 29 percent, in North American over the last 50 years.

Here’s my recent article on it.

The study’s accompanying website is 3billionbirds.org

For the Birds: The serious decline of birds

Even common birds such as robins are declining, according to a new study.

Several articles published last week confirmed what we all knew already: Birds are in decline.

What was enlightening, in a bad way, was the degree to which birds are disappearing. Citing a report from the journal Science, the articles reported that there are 2.9 billion fewer birds in the U.S. and Canada now than there were in 1979. That’s a decrease of 29 percent.

The 2.9 billion fewer birds certainly is startling. The 29 percent decline is also eye-opening, but to be honest, that number doesn’t really surprise me given the percentage decline of some species. The wood thrush, for example, has declined 62 percent from 1966 to 2015, according to the North American Breeding Bird Survey. Its beautiful flute-like song still echoes throughout our woods, but not nearly as often as it used to.

Other startling examples include the eastern meadowlark (89 percent decline), cerulean warbler (72 percent decline), salt marsh sparrow (75 percent decline from 1998 to 2012), and American bittern (42 percent decline).

Unfortunately, examples are easy to come by as nearly every species has declined to some degree over the last 50 years. And don’t even get me started with the birds that are on the brink of extinction, such as the Kirtland’s warbler.

According to the latest study published by Science, waterfowl and raptors are faring the best with slight population increases. That is not surprising considering the amazing recovery of species such as the osprey and bald eagle.

It is interesting to note the discrepancies between this latest study and previous studies such as the North American Breeding Bird Survey and the Partners in Flight study. The previous studies showed stable or slightly increasing populations for many of our common birds. The latest study shows decreases even among birds such as robins and the more common sparrows. The study was conducted by a collaboration of government, nonprofit and educational organizations.

Not that it makes the 29 percent decrease in the overall bird population any better, but part of me thought that the number would be even higher.

What is the significance of this report and why should we care if birds are in decline or not? Aside from the fact that they are beautiful and fascinating creatures, and that millions of people enjoy watching them, there are serious consequences to losing birds. Birds eat insects, pollinate flowers, are a vital part of the food chain and contribute greatly to earth’s incredible biodiversity. They help keep nature in balance.

Birds are also an indicator species, those species that give a picture of the overall health of the planet. If something is wrong with the birds, something is wrong with the planet. And something is certainly wrong with the birds.

To lose nearly three billion birds in a relatively short time signals that changes need to be made. Pesticides, despite our earlier close calls with extinction due to their use, continue to plague the environment. Habitat loss continues nearly unabated and the rapidly-growing world population isn’t going to ease those pressures any time soon. The fires in the Amazon rainforest don’t help either.

Unfortunately, the list of factors in the decline of bird populations goes on and on and on. Fortunately, we have taken notice and that’s the first step toward doing something about it.

Here’s the full report.

Garter snake vs. pickerel frog

I was pulling weeds the other day when I noticed a snake slither out from the greenery. It didn’t go far, however, and I found out why when I looked down. It had already injured a pickerel frog and wasn’t about to let the meal get away. The rest is documented in the video below.

Fair warning: If you love frogs or don’t like seeing the harsh side of nature, don’t hit the play button. You’ve been warned.

Back to school special: New England’s smartest birds

With many schools throughout New England opening this week, I figured it would be appropriate (and fun) to explore the region’s smartest birds.

We all know crows and other members of the corvid family (blue jays and ravens among them) are intelligent birds, but what other species have the gift of intellect? Parrots, of course, can learn and repeat human phrases, but they aren’t exactly New England birds.

I think an argument can be made that all birds are smart because they utilize various strategies to survive in the natural world. According to various sources (which will be named appropriately) found using simple internet searches, however, here are New England’s honor students. As a disclaimer, this is an utterly unofficial list and not to be used in Continue reading
