  1. Phew! I just uploaded the last batch of my lowest priority photos that I took during last month's #CityNatureChallenge. While my last batches of observations don't count towards the official tally, they do help map out these species on #iNaturalist.

    My personal target for this year's challenge was 700 wild taxa and 7,000 observations in the 4-days. In the end I've uploaded 7,276 observations of 963 taxa, of which 6,857 observations and 868 taxa were wild.

    (I reckon 10,000 observations of 1,000 species is probably possible for one person with a lot of planning, even in a relatively low diversity city like Ōtautahi-Christchurch.)

    Next week, I'll see if I can finish summarising all the important new finds made in the City Nature Challenge events in Aotearoa-NZ (there were a lot) and write a post about it on iNaturalist NZ.

    In the meantime, below are three of my favourites of the photos I uploaded, and a map of my observations from the challenge.

  2. The #CityNatureChallenge is still in full swing. While the four days of observing have passed, everyone's now uploading photos and identifying the species in all the observations, The closing date is 10 May.

    Globally the CNC has already topped 2.6 million observations. Here in Aotearoa-NZ 1,715 people have so far uploaded 54,265 observations of 4,494 species, with Wellington currently our leading city.

    If you took any nature photos between Friday and Monday, 24–27 April, there's still time to upload them to #iNaturalist and have them count towards the challenge.

    Me, I've just finished geotagging all my photos in #darktable using my GPS tracks and need to do some photo cropping before I start uploading batches of photos to the iNaturalist website.

    The event is a long way from over. 🙂

  3. A few photos left and I still need to process my audio recordings, but I've definitely surpassed my #CityNatureChallenge totals from last year!

    We also have 7 people who have submitted observations in the county this year, which is the most we've ever had, so that's pretty cool. Hopefully that might be related to the outreach & flyers I did this year, but it's hard to say.

    My 2025 Stats: 322 observations, 202 species or "leaf taxa"
    2026 stats: 370 observations, 252 species

  4. A Hooded Warbler (aka "Monjita") in Prospect Park, yesterday (4/27), a seasonal migrant, like most wood warblers, but not a common bird in our area. Like most songbirds, this ground foraging warbler is in a decades-long decline, but is not considered endangered. This little guy didn't make it easy to get a clear shot, but, hey, you take what you can get.

    He was one of my relatively few observations for this weekend's City Nature Challenge. The Challenge ends today, but so far, in NYC, 12,701 observations were made, comprising 1,399 species, by 665 observers. For Brooklyn, there were 2,512 observations of 670 species by 166 observers. And I am proud to say that one of our students was top dog in Brooklyn and one of the leaders for NYC, with 508 uploads and 175 species.

  5. Well #CityNatureChallenge has turned out great, and I look forward to flooding your timeline over the next few days... or weeks... with some of my photos from it

  6. Today is the fourth and last day of observing species for the #CityNatureChallenge. I’m out the door now taking my cameras for an all-day bike in Christchurch City’s Port Hills, and will then end my day with a moth light at our house.

    What wild species can you find today?

    Keep in mind that after Monday is over we have two weeks to upload the rest of our photos and audio recordings to #iNaturalist and help to identify all the species that have been found.

  7. Submitted several hundred observations for the #CityNatureChallenge :) Currently sitting at number 3 in #wellington :) I still struggle to photograph birds at the best of times, and they seem particularly uncooperative at the moment.. but was quite pleased with a couple.

  8. There are lots of events going on around Ōtautahi-Christchurch and surrounding towns today, for Day 3 of the 2026 City Nature Challenge. See the link below. There’s something for just about everyone.

    I’m heading out in a moment to lead a walk from the Sign of the Takahe in the Cashmere Hills down to the Botanic Gardens (leaving 9:45 from the bus stop). We’re scheduled to pass through the South Library (currently a building site) at 1 pm, and the Art Gallery at 4 pm.

    And, the weather is looking great.

    Whether you’re on an organised event or doing your own thing, any species observations you make that you upload to #iNaturalist today and Monday count towards the City Nature Challenge. Globally the challenge has already passed 900,000 observations since it started on Friday.

  11. Sun has been out, things are melting much faster than anticipated, and it’s even warmed up enough for a few bugs to be around. Feeling much better

  12. Woke up to 22°F, 2-3 inches of snow and tons of ice. Basically worst possible scenario for the #CityNatureChallenge other than an actual blizzard. Bummer

  13. Did you know that your iNaturalist photos can end up in Wikipedia? If you are heading out to take part in the iNaturalist #CityNatureChallenge this weekend, make sure they are added to iNaturalist with a CC0, CC-BY, or CC-BY-SA license. For a lot of species, iNaturalist isn't just a convenient source for Wikimedia projects - it’s the only freely licensed source that exists. 🐝🌳

  15. The observation period for this year's #CItyNatureChallenge has officially begun!

    You may have a half a day or so depending on where you are, but this year's observation period is April 24 - April 27 (this Friday - Monday).

    Hopefully your region is participating, but if not, you can still participate in the global efforts to observe as much wild nature as you can this weekend!

    The uploading and identification period is April 28 - May 10.

  17. The global City Nature Challenge starts at midnight on 23 April, which here in New Zealand is now less than four hours away.

    If you’re new to the City Nature Challenge, it’s four days of observing nature, in hundreds of cities around the world. That’s followed by two weeks of uploading photos and identifying species on #iNaturalist.

    It’s a great way to get together with others and have some fun exploring your city and seeing what wild species you can find.

  20. On Sunday 26 April, I'll be leading another nature walk in Ōtautahi-Christchurch, this time from the Sign of the Takahe to the Botanic Gardens. That's part of the four-day City Nature Challenge.

    It's a terrific walk designed to take us through many of the city's nature filled nooks and crannies.

    Again, all welcome. We leave from the Sign of the Takahe (by the bus stop for the No 1 Cashmere bus) at 9:45 am.

    If you don't have the time to commit to the full walk, you can join us for the first part walking to the South Library, or from the South Library to the Art Gallery, or for the final stint from the Art Gallery to the Botanic Gardens.

    Below are some photos from the previous two years we've done this walk.

  21. Six more #CityNatureChallenge flyers out today, in some of the busiest places in town.

    Really hope we get some more local participation this year!!

  22. I don’t live in a city any more, so it’s more of a Regional. Nature Challenge, but I’m looking working on getting more folks involved in our area this year.

    Last year only 4 people in our whole county participated and I couldn’t promote it as much as I hoped to because I was in the middle of trying to sort out a sudden hard drive failure :(

  23. @3sat Freue mich auf alle Lebewesen, die die kommenden warmen Monate nutzen, um schöne Dinge zu tun. Auf die bunten Käfer und die prächtigen Blütenpflanzen, die singenden Vögel und die flatternden Schmetterlinge, die sprießenden Pilze und die lachenden Menschen...

    Besonders aber auf die City Nature Challenge in #Kiel, #Hamburg, #Koblenz, #Heidelberg, #Erlangen, #Berlin und 700 weiteren Städten weltweit, bei der Ende April all das zusammenkommt!
    #CityNatureChallenge #citizenscience #stadtnatur

  24. @Natur Mir sind bei der #CityNatureChallenge in #Kiel Ende April 2 Carabus auratus über den Weg gelaufen (wortwörtlich). In Essen hab ich einen überfahrenen C granulatus auf dem Radweg gefunden... Also einzelne sind (noch) da.
    Will das Problem damit keinesfalls kleinreden.

  25. After much ado, and eight months after the event itself, here it is. My City Nature Challenge 2025 recap!

    It's long, but it turned out that even though the observations felt slow I still had a lot to learn and say from my first CNC in Oregon.

    Glad to get it out before the new year, if just barely! Please enjoy 🙏🏻

  26. Oh nice, the #CityNatureChallenge is moving to a two-week identification window next year!

    Hopefully that means we get a little better results and some of these big cities that have been posting thousands of bogus observations can be sorted out a little better

  27. Here's one of the 7 moth species new to my garden this #CityNatureChallenge. Big thanks to NZ moth expert Neville Hudson for identifying it. The four I saw in April are the 8th–11th observations of this species from Canterbury on #iNaturalist. It's a NZ endemic species described in 1901 from a specimen collected in Christchurch, so it's not new to the city. Its caterpillars are known to feed on flowers of Pseudognaphalium (a native daisy) and Vittadinia (an exotic daisy). Neither is uncommon.
