6.3 Bird Spike Device
The Bird Spike Device is fastened on top of the WXT520 using the set screw
provided (see Figure 6-2). This device is used to discourage birds from roosting
on the WXT520. It consists of a metallic band with spikes pointing upward. The
spike’s shape and location ensure minimal interference of wind and rain
measurements.
(1) The spikes are designed not to hurt the birds.
(2) While the use of this device does discourage interference from
birds, absolute protection cannot be guaranteed.
(3) When this device is attached, snow may be more prone to
accumulate on the head of the WXT520. In addition, the snow may
melt away more slowly during periods of thaw.
