The number of birds in the United States and Canada has fallen by 29 percent since 1970, scientists reported on Thursday. There are 2.9 billion fewer birds taking wing now than there were 50 years ago.
The analysis, published in the journal Science, is the most exhaustive and ambitious attempt yet to learn what is happening to avian populations. The results have shocked researchers and conservation organizations.
...
Common bird species are vital to ecosystems, controlling pests, pollinating flowers, spreading seeds and regenerating forests. When these birds disappear, their former habitats often are not the same.

I saw an article about this on npr this afternoon, and I admit I'm fighting against getting totally depressed.
We have 3 acres and have left most of them to go wild specifically for ground nesting birds, although the deer spend a lot of time on our place also- including parking young fawns in the wild rose. So we're trying.

I grew upon the south and whip-poor-wills were a common sound in the early evening. In recent visits I no longer heard them. The kind of habitat they rely upon is becoming rare.

Habitat loss AND domestic cats.

Not just feral cats, but those belonging to owners who let them run loose outside. BTW, the mortality rate for domestic cats allowed to run outside is much higher than for those kept indoors. By keeping kitty confined, you are doing a favor for your cat as well as the neighborhood birds!
The western meadow lark used to be common in the Willamette Valley, but is now very rare, thanks to extensive cultivation and use of pesticides. If I want to hear one, I have to go east of the Cascades, or go online here. Efforts are being made to restore some of the original Willamette Valley grasslands to bring back this iconic bird, an indicator species and, incidentally, the Oregon state bird.

When North America is 100% paved over, fracked, clearcut and strip mined, birds will be 100% gone.

This might be true, but I do have some questions.
Aren't there more trees in United States today, than there have been in centuries?
There are many counter examples. Bears and deer are prospering and growing ever more plentiful. Bears were never seen in the 70s where I grew up, but now they are common. Deer were scarce, now they are everywhere.
Candian geese went from being rarely seen to completely commonplace. That's a lot of added bio mass. Too bad we can't turn some of that into food, but they must ingest a lot of pesticides.
I have memories going back 50+ years and I never recall the woods being full of birds. Excluding marshes and wetlands, farms and suburbs seem like ideal bird habit and that's where I've seen tons of birds. But back in the day, people were doing things to support the birds. My grandmother loved to feed birds. Today with our different culture, the suburbs empty out during the workday and maybe we aren't feeding and sheltering them like we used to?
I agree that pesticides are likely a huge problem for the environment, but where is the evidence of this other than apparent declines in bird and insect populations? Why not theories and clear evidence. Also, air quality is fantastically better than it was in the 70s. Our rivers are also much cleaner. Ignoring the whole global warming issue, is the United States environmentally better or worse off since the 70s? I'd say we are much, much better off with the possible exception of invasive species.
Many comments in the comments section of the article said something like, I used to see a lot of birds, but now I don't see any. Nobody said, I now see 30% less birds. Why are folks seeing no birds, when overall decline found in the study was a 30% decline.
I have a feelingly if my grandmother, God bless her, were still here and living in my house, we'd have tons of birds in our back yard. As it is, I see cardinals all the time.
Too bad there is not a good way to know what's really happening.
I'd like to understand if farming methods other than pesticides are effecting bird populations. Maybe harvesting and waste management techniques have resulted in less food for birds?
How are the results geographically distrubuted? What about timing? Are there cycles of highs and lows? Were the results steady or volatile?

I think you raise some good points Bernardo.
As much as each person commenting seems to have their own ideas about the why - including myself - there's really no way to quantify exactly what effect each of the cited causes may have had.
There are now much greater numbers of California Sea Lions and Stellar Sea Lions than there were 50 years ago, but the numbers of their primary food source, the salmon, have declined precipitously.
Some species have proliferated, while numbers of others have continued to dwindle. The raccoon population in urban and suburban areas has exploded, but I cannot recall when the last time was I saw a California Quail.
I find it difficult to believe that the number of Starlings has declined by almost 50%. The damn things are clear out on the coast now, raiding garbage dumpsters at Kalaloch.
I just don't see how there's a way to draw connecting lines between supposed "causes" and what we perceive to be "effect" - I think it's one of those things like the salmon, where there are a number of different causes, all of which have contributed in their own way to the decline in population numbers.

I have seen Canadian geese hunt and kill wild ducklings on the middle fork Snoqualmie. Canadian geese mate for life and are very aggressive and messy. Just my observation.
