birds getting bigger

………………………………….
Birds are getting bigger in central California, and that was a big surprise for Rae Goodman and her colleagues. What’s making the birds bigger? The researchers think that the trend is due to climate change…Climate change may affect body size in a variety of ways, they note in their paper.

For instance, birds might get bigger as they store more fat to ride out severe weather events, which are expected to be more common under global climate change. Climate change could also alter a region’s plant growth, which may eventually lead to changes in a bird’s diet that affect its size.
