It’s In Your Nature: Bird numbers continuing to decline

Recently, the 2025 U.S. State of the Birds report was announced. As you may expect, science and conservation organizations have reported a continued widespread decline in American bird populations.

The decline is across all of our mainland and marine habitats. The report revealed that 229 species are in need of urgent efforts in conservation. That is even worse than the 2019 study showing that there had been a loss of 3 billion birds in North America over the last 50 years.

In a recent column I noted that two lengthy hikes in prime habitat in Carbon County left me very disappointed in an apparent loss of some once rather common bird species. They were birds such as scarlet tanagers, rose-breasted grosbeaks and wood thrush (migratory passerine birds).

The report showed that more than one-third of U.S. bird species are of high or moderate conservation concern. Forty-two of those species have extremely low populations, including some hummingbirds and not surprising, birds like the salt marsh sparrow and piping plover due to the loss of more and more coastal nesting and breeding areas.

Some larger birds, in particular many waterfowl species, are not to be forgotten as their numbers are also declining. We have drained many wetland areas where they breed, feed in migration or where they overwinter.

It is not too late for us to begin and/or continue habitat restoration and conservation.

Locally, although maybe a drop in a bucket, a significant amount of forest land along the Blue Mountain was purchased and then transferred to the Pennsylvania Game Commission. This forested habitat, along a key migration area for songbirds and raptors, will offer feeding areas that are so crucial. The best news is that the land will be protected through perpetuity.

I have been particularly disappointed with the amount of forest, grasslands and farmlands being lost to construction of warehouses, sometimes as large as 1 million square feet. (As you drive through areas just to our south, note how many warehouses that have been built). Even more ironic, note how many have “For Lease” signs. Some of them have remained empty for years.

Solar farms, certainly a cleaner form of producing electricity, can be destructive if we clear 500 acres of forest (in a local township) to erect solar panels.

I think local municipalities, and all of us, should carefully consider where we will place them. Maybe they can be placed on reinforced rooftops of warehouse already in place. Why take away crucial habitat and, even worse, carbon dioxide gobbling forests, which are so important in reducing the greenhouse effect.

Our songbirds also must somehow in their nighttime migrations find a way to navigate around glass walled skyscrapers and apartments in our cities like Chicago, New York and even Philadelphia. Massive forest fires in Canada have not helped either in the past few years. Millions of acres have been lost.

Remember, it doesn’t happen overnight, but within a few years those forests will regrow and bird species may find even better conditions to breed. That forest regeneration can’t happen if we cover once good habitat with blacktop and sprawling warehouses.

I try to avoid these controversial topics but I believe we all need to see that if bird populations are dropping, that serves as indicators of threats to human welfare as well.

Birds, such as the wood thrush or the orchard oriole shown here, are finding forest fragmentation in North America, and especially deforestation in Central and South American, as causes for their recent population declines. BARRY REED/SPECIAL TO THE TIMES NEWS
It is widely known that lengthening and shortening of daylight hours keys when birds migrate. Still, using this instinctual behavior will send birds northward after many of the trees are in complete foliage. This global warming caused effect makes it more difficult for black-throated green warblers to find adequate food for them and their broods. The tasty caterpillars on emerging leaves that they eat may have already pupated.
I imagine most of us are getting tired of the rapid loss of grasslands, farms and forests to the explosion of warehouses across Pennsylvania. All these lead to the big drop in bird and other wildlife populations.
About 1 billion birds are killed each year when they strike windows in the United States. One night in October of 2023 more than 1,000 birds, many of them red-eyed vireos, were killed at one building alone.
American widgeons and many other duck species’ numbers are dropping because of the continued loss of wetlands across North America.
