The Heat Is On: Climate Change Causes Birds To Hatch Early (australiangeographic.com.au)
grrlscientist writes: A recently published study reveals that climate change can cause birds' eggs to hatch early. In addition to creating warmer temperatures that trigger early embryonic development in birds, climate change also increases the frequency and duration of heat waves. Thus, warming temperatures are leading to asynchronous hatching of individual eggs within a clutch and increased chick mortality, particularly for birds breeding in the tropics and semi-tropics, and in tropical deserts.
This is a fairly significant problem for parts of Northern New Mexico through Central Colorado. I think though that it's kind of the opposite timing from what you describe. The Spruce Beetle larvae are spawning at an earlier time. The eggs of birds who primarily predate on them to feed their young aren't hatching early enough (they're hatching earlier, just not early enough) and are actually dwindling due to starvation while the infestation gets larger. The pine beetle infestation is even worse.
It's rather stunning to see mile after mile of dead forest in parts of central Colorado.

Probably because of this "Thank you for visiting Forbes. We noticed that you have an ad blocker enabled." Which makes the site useless to many of us.
Time is what keeps everything from happening all at once.
The paper was about the effect of temperatures on the nesting success of zebra finches. As part of the study they looked at natural conditions but they also tested the effects of artificially raising the temperature. The paper barely mentions global warming.
