While the Arctic Warms, Migrating Birds Pay the Price in the Tropics

Red knot birds are becoming smaller as temperatures warm in their Arctic breeding grounds. But the migrating birds don’t pay the price for this climate-caused shrinkage until they arrive at the more stable climate of their tropical winter homes. According to a new study by Jan van Gils and colleagues, the smaller red knots have shorter beaks that prevent them from reaching quality mollusk meals deep in the tropical sand, forcing them to subsist instead on lower quality mollusks and seagrass. As a result, survival rates are down among red knots born in warm Arctic years, the researchers note. The red knots are one of several animals to shrink in size in response to climate warming. Newborn red knots depend on a “bloom” of insects that appears after the Arctic tundra melts as their main supply of food, but climate change has pushed this bloom earlier and out of sync with red knot hatching. Van Gils and colleagues’ 33-year study of migrating red knots confirms that birds born in warm and lean Arctic years arrive in West African wintering grounds with shorter beaks that can only dig up one-third of their available preferred prey. Snowmelt in the red knot breeding grounds is occurring earlier and earlier, changing at the rate of about half a day per year, the researchers say, and this warming could be affecting the survival of other migrating animals beyond the red knots. In a related Perspective, Martin Wikelski and Grigori Tertitski discuss the implications of this new “global ecological warning sign.”

  1. It is “possible” that the hoaxers “may have” painted themselves into a corner.

  2. Imagination is necessary for writing good fiction or producing an award winning movie or play, but it has no place in making wild conclusions in science.

  3. Today’s typical global warming reporting formula.

    1.Scientists Write a report filled with may, could etc.
    2.MSM reporters skip all the may’s and could’s and report that the study found conclusive evidence.
    3. The White House then declares that the report proved that millions of birds have died.
    4. The MSM then parrots #3.
    5. Children are then taught 2,3 and 4 in school.

  4. So did short beaked individuals suffer in the colder climes when it was colder, thus reducing their viability at the COLD end of their migration – so they weren’t around to be studied at the WARM end of their migration? And has the overall population suffered?
