Loaded!

Day 285: "Attention! Attention! Calling all Cedar Waxwings! The feast is on the table!" Both of my Mountain-ash trees are loaded...and I do mean LOADED...with fruit, to the point that I am afraid some of the branches may break under the weight. I don't think I've ever seen as heavy a crop. The Waxwings failed to appear last year (they're intermittent here), which meant that the robins had a banquet, but the trees were not this heavily laden. There's plenty here for everybody this year, if only the Waxwings will notice. What brings them here some years and not others? Are they responding to visual clues like this tree is surely offering? Or do they navigate from waypoint to waypoint with built-in GPS, having marked good food sources during spring migration? What keys them in? Perhaps I should hang out a big neon sign saying, "Waxwings welcome," if this glowing orange invitation doesn't suffice.
