Why, you may ask are nesting boxes not as common in New Zealand as they are in countries in like England and the United States. The answer is simple. Most nesting boxes put out by backyard enthusiasts attract exotic birds such as Sparrows and Starlings. It is not surprising therefore, that people do not want to attract these birds to their gardens, especially if they are in bushy areas such as Wellington. There is a growing belief that some natives will use traditional nest boxes if they are specifically modified to suit their needs. The Grey Warbler and Silvereye may like open fronted boxes, Tui have been known to investigate nest boxes and boxes with larger openings may attract Little Owls or even Moreporks. Kakariki and Kaka may be attracted to some nest boxes with the correct sized openings but so too will the Eastern Rosella, which is more common in Wellington. The jury is still out however. Bird houses are probably not an advantage to the native populations except when placed by experts in specific locations. Ducks Unlimited for example have had some success with the Grey Teal and Mallards. But there is an artistry to bird houses and even if not used for any purpose can be fun to build. The important point however, is if you don’t want exotic birds using them – don’t create on opening.
The cache is one example of a house just built for the fun of it but it is not for the birds. There is a trick to opening it. It does open. It does not require tools and should not be treated too harshly. Use the brain rather than the brawn. And a little patience. BYOP
The cache is down a new track that will eventually link Downing Street and the Skyline near the Crofton Downs Substation to Spencer Street/Silverstream Road. If you want to go and help complete the track turn up on Saturday morning after 10am. There is a small, muddy (unofficial) access to Spencer Street while the track is being completed, from near the current terminal point.
