They are up to 5,000+ dead blackbirds now in that one town.
I find that highly disturbing. If it was 5,000 across the USA, it would be worrisome and sad but somehow in one place (and then more in another place) gets the "alarming" label for me.
Don't forget all the fish-kills and how they now think the mass bee extinction is from seemingly EPA approved pesticides.
I listened to an explanation of this earlier (I will see if I can find documentation) -- the blackbirds travel in extremely large flocks and follow a leader very tightly (much closer in proximity to each other than most birds). The birds travel at night and can be disoriented by things such as fireworks, lightning, or other flashing lights. If the leading bird is disoriented, it could cause the bird to fly directly into the ground, a building, or any other large bird-killing object. This leads to an almost lemming-like mass suicide of the flock.
I also believe that it has been documented to have happened fairly regularly. The numbers I heard today were 16 times in the past 30 years there has been a mass death of over 1000 birds.
5,000 birds across the country? That's about one for every area the size of Rhode Island. Blackbirds are the most abundant kind of bird on this continent. A few thousand here or there is literally not going to make any difference. This is not nearly on the same scale as the bee crisis.
Edit: Even if there are only 10 million blackbirds living at any given time (I'm sure there are more), and they have a lifespan of 5 years, that's a turnover of 5,400 on an average day.
Considering a flock of blackbirds can consist of several million birds, 5000 aren't actually that many. Numbers like that are only relevant in context.
The deaths aren't worthy of concern and investigation only if they're linked.
They're worthy of concern and investigation in each instance because history has shown they tend to happen for one of two reasons: severe weather shock or human activity.
Thus we need to carefully consider and investigate each occurrence, lest we ignore the metaphoric canary in the coalmine on the grounds that 'canaries die all the time'.
Truly the news cycle has latched onto an easy-to-sell trend and narrative. But their behavior, and the laughable connections they imply, don't speak to whether or not any given mass animal death truly is a non-issue.
The canary in the coal mine is only useful because there's only one plausible explanation for it keeling over. If they died all the time for no good reason they'd be useless. It might be really cool if we could extract signal against a noisy background but there's mathematical limits on our ability to do that even in theory, and we're generally better off looking at the less noisy signals.
Plus chasing noise turns out to be really dangerous. 5% of the time or so, random processes will correlate with something else you look at with 95% confidence. Your suggestion is not a good idea at all, it's a recipe for spurious connections and wildly disproportionate responses, no matter how good it feels to a human brain.
The google map linked in the article[1] contains many entries that don't quite fit the oddness of some of the die-offs people are talking about. For example, [2] refers to 150 tons of tilapia that died because of being farmed too densely. [3] refers to fish that died when a small city lake froze over with a bunch of decaying leaves trapped under the ice releasing methane. And others.
Because you can only conspiracy-theory about what you've noticed. They don't actually notice anything new, or at least not very much new, the essence of conspiracy theories is to weave existing readily-visible facts and a healthy dollop of made up fantasy into some new theory. From what I can see they hardly ever do anything like a real investigation and even when they do there's a lot of the aforementioned fantasy in it. Like, someone writes a book in which they claim to have spent a lot of time investigating UFO issues but it's still mostly just regurgitated theories and a few allusions to trying to get more info but mostly not. Info mostly just circulates and gets endlessly chewed on, very little new info gets added into the morass by the actual conspiracy theorists from what I can see, with a handful of exceptions.

the NWHC has quarterly reports on wildlife mortality dating back to 1995 online (and they claim to have records back to 1975 in databases).

Come to think of it, how would one classify RWW? "All the news that's currently popular"?
