NatureWatch NZ is coming!

We've been hard at work here at NZBRN over the past year working on our replacement to our current web bio-recording system. We've joined the open-source iNaturalist project and have been busy optimising the system for New Zealand and adding on legacy NZBRN features you've come to depend on. It's looking really good and we are on track to launch in August. Here's a quick peak at the new features we'll be introducing.

First, a brand new and shiny system deserves a shiny new name. You won't need to be NZBRNing on your next tramp. Now you can NatureWatch.

Built by NZBRN | powered by iNaturalist
We decided on NatureWatch NZ after an extensive and surprisingly emotive debate and vote amongst a selection of 85 of our keenest users and supporters (thanks everyone!). Initial suggestions playing on our new iNaturalist connections, kiwiNaturalist and nzNaturalist, were shot down by people concerned they'd be obligated to do their nature watching without any clothes.

So what will the new system be able to do for you? Check out these great new features, baked right into the iNaturalist DNA by the clever iNaturalist developers.
More...
  • Photo uploads! Upload to NatureWatch NZ directly or connect to us from your Flickr or Picasa web galleries.
  • "ID please"! Flag you observations with photos as ID please and other NatureWatch users will suggest identifications.
  • Challenge and agree with IDs! Crowd-sourcing at its best, NatureWatch NZ lets everyone correct the errors they see in each others observations.
  • Comment on observations! Do you want to know how someone got that amazing photo? Or how they got so close to such an elusive animal? Start up a conversation.
  • Follow other users! If you discover another NatureWatch NZ user making interesting observations in your area, or of species you're really interested in, you can follow them to automatically see all of their new observations.
  • Join and create projects! Get together with like minded people in a project. It could be your community restoration group. It could be your school nature watch project. It could be fans of jumping spiders.
  • Life lists, and species lists per place! You can easily use NatureWatch NZ to view a list of all the species you've recorded. You can also browse places and see a list of all the species found there. If NatureWatch NZ doesn't have the place you want, you can make it by drawing a polygon on our map.
  • iPhone and Android apps! Because, seriously, who carries a computer out into the wild. If you've got a smart phone in your pocket, add your observations on the spot, whether you're online or offline.
NatureWatch NZ

You can pop on over to iNaturalist and get an idea of what NatureWatch NZ will offer. But we'll also do more than that. We're busy at the moment getting NatureWatch NZ hooked up to the about-to-be-launched New Zealand Organisms Register, so you'll be able to record an observation of any species in New Zealand, be it a silvereye or a starfish. Plus we're making it easier for you to record more details about your observations, like what species it's eating. And we're working on a list of refinements and new features that we'll continue to release over the next 12 months after NatureWatch NZ is available.

We're all very excited. This is everything we wanted when NZBRN started in 2005, and a whole lot more.

Helping watch the world's biodiversity

NZBRN was part of the recent workshop in Lincoln and Christchurch on GEO-BON, the biodiversity observation network (BON) of the United Nations Group on Earth Observations (GEO). GEO-BON is attempting to establish a global biodiversity observation system to better track biodiversity changes. Biodiversity remains the poor cousin of more thoroughly monitored environmental factors like carbon, nitrogen, climate, and fresh water, despite the world being on the cusp of the biggest extinction event since the loss of the dinosaurs. GEO-BON is trying to change that. Henrique Pereira of GEO-BON visited New Zealand to learn about how we do things here.

Henrique started the NZ BioData workshop by introducing us to the problem. It's alarmingly difficult to get a global-scale picture of the biodiversity crisis. Even assessing land cover changes on a global scale is difficult, as the necessary information is scattered. The few high-quality, large-scale, long-term biodiversity datasets, mostly from Europe and North America and strongly biased towards vertebrates, paint a grim picture of widespread ongoing declines in most groups. We need comparable long-term data from a wider variety of groups across the whole world to properly assess the true extent of the biodiversity crisis. Henrique's suggestion is to set up some simple monitoring of birds, butterflies, and plants across a global network of repeatedly visited sites.

It was clear in the workshop that New Zealand is leading the world in many aspects of biodiversity monitoring, especially with the Department of Conservation's Natural Heritage Management System (NHMS) that has begun to repeatedly visit a grid of plots across all of New Zealand's public wildlands. By collaborating with New Zealand's carbon monitoring programme (currently called LUCAS), DOC is monitoring detailed biodiversity information from public wildlands in an 8 km square grid across the whole country. We will be well placed from this to record how native and exotic biodiversity in these plots changes over time as environmental change accelerates (climate, nitrogen cycle, phosphorous cycle, biological invasions, etc.).

NZBRN was well represented at the workshop and I gave a talk about what NZBRN has achieved since we began in 2005. I also gave an overview of where we're heading with our new iNaturalist-based system, which will be launched later this year. You can see a copy of my talk here. (We were pleased to learn that Henrique was well-familar with iNaturalist and they were already in discussions with GEO-BON.)
NZBRN talk at BioData Workshop
Here's a copy of our talk on NZBRN at the BioData workshop (3.5 MB PDF).

Henrique concluded that it is a myth that the data is out there to be collated. There's a big role for "citizen science" in collecting data, and most of the long-term biodiversity datasets we have globally are collected wholly or in part by volunteers (just like New Zealand's excellent bird atlas project of the Ornithological Society of New Zealand and the garden bird survey). It's up to us all to collectively open our eyes to the nature around us and watch how our activities are changing the world.

Where are the fantails that survived the big snow?

Our unseasonably warm winter was interrupted by two ferocious southerly storms that dumped snow across much of New Zealand. My home town of Christchurch was buried for days while raked by strong, chilling winds fresh from Antarctica. While we all had the luxury to bundle up inside our houses around our fires or heat pumps, wild nature was left outside to struggle through the storm. As in past late winter snow storms, it looks like fantails have been hit particularly hard (except for three desperate, clever birds that sheltered inside someone's house).

I am an avid bird counter (my wife would say obsessive) and I've yet to see a single fantail since the second big snow, which ended over a week ago. On my weekly runs between Wigram and the Cashmere hills, I almost always see fantails. I've done two runs since the snow, and no fantails. On my bike into work at Lincoln, I usually see fantails, almost always when I go the long way through Tai Tapu. So far, three rides, including through Tai Tapu, and no fantails. My wife saw one fantail at Victoria Park yesterday, just one, after we've spent several hours in combination there since the snow.

How about you? Have you seen fantails? Where? Now is the time to use NZBRN and record where you are seeing, and equally importantly, not seeing fantails. When using NZBRN, you can tick the "Sought but not found" box to mark places and times where you looked for fantails unsuccessfully.

This is an important opportunity to learn where in our landscapes most fantails survive these storms. Fantails are prolific breeders and eventually bounced back after the big 1992 August snow storm. It is quite plausible that some places are where most of the survivors are, and these places play a disproportionately large role in the population's recovery. Perhaps it's sheltered dense lowland forests on low northern slopes facing away from the storm (not that Christchurch has any of them left). In Christchurch, perhaps it's Bottlelake Plantation, a large lowland pine plantation that presumably is partially sheltered from the worst of the winds and snow by Banks Peninsula. Perhaps it's sheltered well-wooded gardens without cats.

Only lots of your observations can tell us this.

Go the All Blacks?
In the South Island, we have both pied and black phase fantails. The black birds are found only rarely in the North Island and are associated with the colder climes here in the South Island. If you decide to record survivors of the 2011 Big Snow, it would also be useful if you recorded in the NZBRN comments whether each bird you see is pied or black. Perhaps the black birds, by soaking up more sunshine, were a bit better able to cope with the recent bleak conditions. The fantail population may become more black just in time for the Rugby World Cup!

It's bird spotting time!

It's time again for the annual New Zealand garden bird survey. You've got until this Sunday (3 July) to add to the annual national effort to document birds in our gardens. All you need to do is spend one hour noting the maximum number of each bird species that you see at any one time.

Eric Spurr, the project coordinator, told us the following about last year's survey.

Silvereye returned to the top of the table of species counted in greatest numbers, with house sparrow second, starling third, and blackbird fourth. A grand total of 187,858 birds were counted in 4193 gardens (an average of nearly 45 birds per garden). This included 55,543 silvereyes, 52,779 house sparrows, 11,837starlings, and 11,156 blackbirds. These species have been the top four in all four years of the survey. As in previous years, the only other native species apart from silvereye to make the top 10 were tui and fantail.


These annual surveys are a useful way to document which birds are using our gardens and how our bird communities are changing.

Instructions and a summary of past years' findings can be found at the New Zealand Garden Bird Survey. The results of the past bird surveys are all available through NZBRN (Eric is still following up on some unusual observations in the 2010 data).

If you miss this survey or get enthused about documenting the birds using your garden at other times of the year, you can store and share your garden observations on NZBRN at any time (and not just of birds but also other animals, plants, and fungi). If birds and only birds are your thing, another good web option is eBird.

NZBRN distribution maps come to nzbutterfly info

Those of you who like butterflies have likely already discovered Robert Arter-Williamson's excellent compendium of information at www.nzbutterfly.info. There's lots of information about all of New Zealand's butterfly species. You can now also view live NZBRN distribution maps for each species from the webpages of www.nzbutterfly.info.

For example, if you go to the red admiral page, you'll see an NZBRN logo on the right-hand column. Clicking it will pop up a map showing all red admiral observations in NZBRN. Handy!

If you want to add maps like this to your own website, we have a blog post of instructions all about it.

The other thing you'll note if you explore these maps is that we need a lot more observations to properly map out the distributions of these butterflies. Get ready to spot butterflies in the spring, and if you have any old butterfly observations, please consider sharing them with the world using NZBRN.

How old is that bird?

Those of you entering bird records may have noticed that NZBRN has an unusually detailed list of options for Age.

This is generally met with confusion by non-birders, including me. What it means is a bird's minimum age in years. If a bird is within the first year of its life, it's 1cy (unless it's an egg, or a chick if it hasn't fledged). If it's one or more years old, but you don't know how old, you should use 1cy+. If you know a bird is more than one year old but less than two years old, use 2cy. And on it goes. If that's a tad too obtuse, you can just choose from egg, chick, 1cy for fledged juveniles, and adult. (You can also leave Age blank.)

How would you even know how old a bird is? Some species have distinctive signs in their plumage in the first few years of life. For example, all blackbirds start out with brown plumage and dull-coloured beaks when they fledge in spring-summer. In autumn, the male birds moult their plumage to become black, except for their primary flight feathers on their wings which remain brown (have a careful look at the first photo above). At around this time, they'll take on the yellow-orange beak colour of adult birds. In the second year, male blackbirds moult again and take on their distinctive complete black plumage. So, it you'd got a brown blackbird with a dull beak colour, it's 1cy. If you see a black male with an orange beak in spring or summer that still has brown primary feathers, it's 2cy. If it's an all-black male, it must be more than a year old so it's 2cy+.

For older birds, your only hope of aging them is if some clever ornithologist caught it in the past and banded it. Whenever you see colour bands on a bird, it is exceptionally useful to record in your comments the colours and their order on both the right and left legs. If you find a dead bird with a metal leg band, it's also very helpful if you send in all the details including the band number to the National Banding Office at the Department of Conservation.

More...
In these abbreviations, "cy" means "calendar year", which is a hang-over from northern hemisphere ornithology (and the Swedish web code origins of the current NZBRN system). Bird breeding seasons up north conveniently span one calendar year from spring to autumn, Seasons in the Southern Hemisphere do not behave so well with our Northern Hemisphere calendar. When you use NZBRN, "1cy" still applies to <1 year old birds, etc.

NZBRN newsletter

Our latest newsletter is now available. We are very excited to announce that we have secured one year's funding from TFBIS, part of the New Zealand Government, to begin a complete refresh of the NZBRN website, from its database foundations to a simpler, more user-friendly, and more flexible website. We describe our first steps in the newsletter, which most importantly involves getting feedback from you.

We would really like to hear about your priorities for the new NZBRN. What would you change? What treasured features would you retain? The newsletter contains a one-page survey asking for your feedback. You can also download an editable PDF of the survey form that you can fill in on your computer and email to us. We look forward to hearing from you.
