Those sticks all come from trees. The male will fly to a dead limb or stick and grab hold with his talons and then just take off. It's a pretty awesome thing to watch. He then flies back to the nest site and places it on the nest. When the female comes back, she may rearrange some of the sticks if she doesn't like where the male put them. Sometimes all they do is add another layer to the nest if it survived the winter, which is what the pair by the salt marsh did (the osprey in the pic is from that pair). Sometimes the nest gets blown down by a winter storm and they have to do a complete rebuild, which is what the pair on the island (our showcase pair) had to do this year. The male arrived back on March 31st, and had the thing rebuilt within ten to fourteen days. He's very industrious.
