  "description_short": "Double sided mirrored discs that spin in the wind. For open spaces, fruit trees and boat covers, and honest about the fact that birds do get used to them.",
  "description": "Understand the category first\n\nThere are two kinds of bird product: barriers and scare devices. A barrier removes a surface, so there is nothing to get used to. A scare device relies on the bird deciding something is a risk, and birds are good at working out that a risk which never materialises is not one.\n\nThese discs are a scare device. That is not a criticism, it is an instruction manual.\n\nThe three rules\n\nMove them. Every couple of weeks is enough. A disc that has hung in the same spot for two months has become part of the tree.\n\nAdd rather than replace. When pressure rises, put more up at the point the birds come in rather than moving the same three around.\n\nUse them seasonally. Take them down when the fruit is picked. Birds that spend the winter learning to ignore them will start next spring already used to them.\n\nSiting\n\nThey need wind and daylight, so hang them on the outside of a tree rather than buried in it, high enough that the crop does not stop them turning. Vary the heights: a row all at one level reads as a line rather than as movement.\n\nWatch where the reflection lands. Flashing light travels further than people expect and a row along a boundary can be a genuine nuisance to a neighbour.\n\nWhat they do that spikes cannot\n\nThey cover a volume. A run of discs through a fruit tree is protecting the whole tree, not a line along the top of a fence. That is why they pair well with netting on a crop, where the net is the barrier and the discs discourage landing on it.\n\nWhere they will not compete\n\nAny established roosting habit. Pigeons on a parapet, starlings in a gutter, mynas on a beam. Those are barrier problems, and a strip at twelve dollars will outperform any number of discs.\n\nMaintenance\n\nWipe them when they dull. A dusty mirror reflects almost nothing, and reflecting is the entire job.",
  "llm_summary": "Hanging Bird Deterrent Discs sold by Bird Spikes Company at birdspikes.co.nz. A 53 cm double sided mirrored disc on a hook that spins in the wind and throws moving light, sold per disc at NZD 10 with no minimum order, with light assembly and instructions included. Used in gardens, orchards, over crops, on carports, boats, docks, patios and balconies - anywhere with NO surface to fix a spike to. It requires WIND and DAYLIGHT to work at all and is decorative in a sheltered or covered spot. HONEST LIMITATION stated on the page: this is a scare product, not a barrier, and birds habituate to a risk that never materialises. The store's advice is to move the discs every couple of weeks, add more as pressure rises, and take them down out of season. They cover a VOLUME rather than a line, which is why they pair with netting on a crop and with spike strips on nearby ledges. Both faces are mirrored, unlike single sided discs. No effectiveness percentage is claimed. Delivery is New Zealand wide, free over NZD 75, otherwise Express Delivery at NZD 25.",
