Our two different Swallows weathervanes, designed and made for the first time at the end of last year. Initially, the idea of having the birds flying over either the trees or rooftops was mostly just to raise them off the bar a little while still having a decent area to weld to, therefore keeping the design strong without the use of support rods. This also adds a bit of extra surface area for the wind to catch. Though now I think both ideas really add to the design, almost setting a scene. So far, the tree tops variation has been the more popular, I think possibly because many of our customers live in the countryside rather than cities.
