    I visited this spot recently and turned left instead of right. With the sunrise, that was a mistake because the sun was in my eyes looking into the wetlands.

It's definitely worth thinking of the angle of the sun when choosing when and where to bird.

    This video was fantastic. I often find myself lending out a spare pair of binoculars to friends who havent done much birding, and this is a constant challenge. I will sometimes use pointing for a distant bird, but to do so requires us to stand next to each other, and to have our heads very close together and looking in the same direction, so they can actually look down the end of my arm, past my pointed finger, and follow it to where I'm pointing at. Last year during a Christmas bird count, while straining to see a skulky LeConte's sparrow in dense grass, our crew leader did something that left me speechless. Don't try this with a bird that is very close... you may scare it with all the moving around. He looked right at the bird, had me stand directly behind him, and told me to point my binoculars at the back of his head. Once I did so, he bent over (I suppose in a more fragile situation you could take a quiet step to the side) and right where I was looking, where the back of his head had been, was a LeConte's sparrow. it was like a magic trick.

    • @DuPageBirdingClub
      @DuPageBirdingClub 3 года назад

      We can't find anything that compares the lengths of those serrated edges of merganser bills--tomium is the word for sharp cutting edge of the bill, btw. The bill of the Common is wider at the base than Red-breasted, and there's a sharper hook at the end of the Common's bill, but it is unclear if any of that translates into any difference in serration length.

    • @doppelhelixes
      @doppelhelixes 3 года назад

      @@DuPageBirdingClub the sharpness of the hook shows there is preasure to evolve longer grabing tools. The wider base suggests they eat larger fish - therefore biger seration. The shorter base suggests smaller, faster prey - therefore not as long tomium needed. It is just an educated guess, but this is good enough for my purposes. I just hope hybrids can produce fertile males (or even both) but data on fertility of hybrids is hard to get, specially with specific waterfowl.
