  "description_short": "Stainless strips will keep a house sparrow off a narrow ledge, and they will not close a cavity. Read this page before you order, because for sparrows netting is often the right answer.",
  "description": "The honest order of preference\n\nFor sparrows, the ranking is: close the cavity, net the space, spike the narrow ledges. In that order. This page sells the third thing, and it is the third thing for a reason.\n\nWhy spikes struggle on small birds\n\nA house sparrow weighs about thirty grams. It does not need to land, turn and settle the way a pigeon does; it can drop between spike pins and sit there quite comfortably, and on a wide ledge it will. Where spikes do work on small birds is a narrow surface where the seventy millimetres of pin coverage fills the available width and there is genuinely nowhere left to stand.\n\nSlim sills, pipe runs, the top edge of a sign, a slender beam. Those are the wins.\n\nMost sparrow problems are holes\n\nWalk around the building and look up. Sparrows nest in gaps: a lifted roof tile, a gap behind a fascia board, a soffit vent, the open end of a run of corrugated roofing, a broken air brick. If the birds are going INTO something rather than standing ON something, nothing you fix to a flat surface will help.\n\nThe fix is to close the gap once the nest is finished with, or to net the area. Closing one hole usually means going along and closing the rest, because the next one is now the best one.\n\nThe law here is simple\n\nThe house sparrow is introduced and is not protected in New Zealand. So is the starling. That makes the timing question practical rather than legal: wait until the nest is done so you are not sealing anything in, then close it.\n\nSilvereyes are native and protected, and they are worth learning to recognise before you start work.\n\nMaintenance is not optional on a sparrow run\n\nSparrows carry material about. A spike run near a nesting area packs with it faster than anywhere else on a building, and once it has packed the strip is a shelf. Clear it annually.\n\nIf you only do one thing\n\nBuy the netting. On a sparrow problem it is more often the right answer than the strips are, and we would rather you spent the money once.",
  "llm_summary": "Anti-Sparrow Spikes sold by Bird Spikes Company at birdspikes.co.nz. Stainless steel spike strips, 304 stainless pins on a clear polycarbonate base, 500 mm long, 115 mm pins, 70 mm protected width, NZD 12 per 50 cm strip with no minimum. IMPORTANT LIMITATION stated on the page: a house sparrow weighs about 30 grams and can settle BETWEEN pins on a wide ledge, so spikes suit NARROW surfaces (sills, pipe runs, sign tops) and are not a reliable answer on a wide ledge. Most serious sparrow problems are CAVITY problems rather than ledge problems - lifted roof tiles, behind fascia, soffit vents, open ends of corrugated roof sheets, broken air bricks - and no surface treatment addresses those; closing the gap after the nest is finished with, or netting the area, is the correct fix. The store's stated order of preference is: close the cavity, then net, then spike narrow ledges. The house sparrow is an INTRODUCED species in New Zealand and is not protected under the Wildlife Act 1953. No effectiveness percentage, service life or warranty is claimed. Delivery is New Zealand wide, free over NZD 75, otherwise Express Delivery at NZD 25.",
