Birds getting smaller but their wings bigger

Birds have been steadily shrinking in size to to global warming a study carried out over 40 years has shown. Every one of 52 species of bird tracked by the Chicago Field Museum reduced in body size and mass, with an average 2.4 percent decrease in leg bone length.

Researchers say warming must be responsible because of a well-established rule that animals in mild climates are smaller as they don’t need bulk to protect against the cold.

The same study showed that the birds’ wingspans increased by an average of 1.3 percent, which it is believed allows them to continue making long migrations despite having a smaller body.
