Issue Five - June 2015

Welcome to the fifth issue of the Auckland NZ dotterel minders newsletter

Apologies for the next issue coming out so soon after the last. However there is some important news to share. 

There were some data entry errors in the data sent out in the previous issue. Thanks to those people who pointed them out. Those few minor changes meant that there was a recalculation of the breeding success results.

Here's a quick summary of the new results

  • 75 fledged chicks were produced from 99 breeding pairs
  • This gives a regional breeding success result of 0.76 chicks per pair
  • Breeding success for sites with management usually produce 0.5-1 chicks per pair
  • This is a better result from last season's 2013/2014 year of 0.69 chicks per pair
Thanks again for all the effort and time you have all put in to help protect our NZ dotterels. This great result shows that the management of these sites is working, and illustrates that it can only have been achieved by the effort from staff and volunteers.

Below is a more in-depth look at what is happening around the different breeding sites:
 
Site Pairs  Summary of nests Comments Observers
Te Arai 10  12 chicks fledged  
Gwenda Pulham & Heidrum Schinke
Omaha 17 8 fledged and likely more than this
Omaha spit is difficult to monitor as there is a high density of breeding pairs as well as it being a flocking site for non-breeding "teenagers".
 
Marie Ward & Sue Cook
Tawharanui 10 13 chicks fledged from 44 eggs. Nests lost 1 lost to tide, 1 lost the high wind, 1 mid dunes lost most likely to heat, 2 nests had 3 eggs vanish where harrier were observed, 1 nest with 3 eggs did not hatch.      Big improvement on last year with some management of BB gulls and use of upturned garden hanging flower baskets woven with flax and garden staples attached as legs. These were installed near nest sites that lacked any protection for chicks. Drift wood logs were also dragged into enclosures.
 
Alison Stanes, Sharon Kast, Cheri Crosby
Te Muri 4 None Nests lost to tide inundation, predation and abandonment Sue Davy and Don Sutherland
 
Wenderholm 5 None Nests lost to tide inundation, predation and abandonment Sue Davy, and Don Sutherland
 
Waiwera 5 3 chicks fledged Dog predation of chicks still the dominant problem Sue Davy, Don Sutherland, Bob and Jenny Kelly
 
Shakespear 5 5 nests, 13 eggs, 2 eggs lost, 11 hatched, 10 chicks fledged Had to do some nest shifting and sandbagging over season, but otherwise beach nests fine. Spur winged plovers appeared to prevent dotterels from nesting in paddocks, persistently chasing the dotterels away. None of the potential paddock sites where dotterels were showing interest ended up with dotterel nesting, except for one paddock nest located, egg and dotterels disappeared a week later, thought to be due to presence of spur-winged plovers. On the evening of 8/1/15 there were 21 Dotterels on Te Haruhi Beach.16 were our birds with the addition of  2 adults and 2 newly fledged chicks from elsewhere
 
Jan Velvin
Whakanewha 4 4 chicks fledged from 3 nests (2 from 1 nest and 1 survivor from 2 other clutches of 3). All fledglings hatched in December. 
 
1 VOC chick, 3 pied stilt chicks and 3 banded rail chicks also fledged in dotterel protection area.  Jonah Kitto-Verhoef
Albany 9 13 chicks fledged   Gwenda Pulham & Heidrum Schinke

 
Ambury 1 1 definitely fledged, maybe 2 others from the same clutch also fledged but not confirmed.
 
  Kevin Barker
Whatipu 5 6 fledged   Darryl Jeffries
 
Bethells 2 Birds nest well into the dunes amongst the spinifex about halfway down the main beach at Bethells Noted two pairs of NZ dotterles feeding on the ebach on 22 October 2014 with one fledged bird. When checking the stoat traps and rabbit bait stations in the dunes the dotterels are regularly heard and seen in the dunes and also flying between the beach and dunes. Over the breeding season from August to March predators caught in the Bethells beach dunes numbered 20 rats, 6 stoats, 6 weasels, and 14 hedgehogs
 
Greg Hoskins
Scandretts Bay 4 2 Fledged.  Multiple egg and chick losses all season.  Nearly all to predation
Suspects unconfirmed however cat captured adjacent nests after chick losses.  Also 1 adult incubating pair disappeared at same time – regular Scandrett birds and quite likely lost 1 or both birds to same cat.  Other reports of stoats seen in nesting areas, stoats also caught near nesting site, plus red billed gull suspected of taking some eggs.  Hedgehogs captured on park during nesting season also – first time for number of years here.
 
David Edge and Alan Seelye
Goldsworthy Bay 2 Possible fledging but unknown Not heavily monitored but pest control is carried out there too. David Edge and Alan Seelye
Motuora Island  7  6 nests all laid 2-3 clutches but either eggs disappeared or the chicks disappeared in 1 – 2 week – only one pair suspect fledged their chicks
The westerly winds and weather suspect took there toll on eggs in nov- dec . then dec suspect that the influx of campers / day visitors on the beach and influx of seagulls that come with the camping influx may have contributed to the lack of eggs hatching or chicks reaching maturity.Possibly one pair fledged their chicks. Not confirmed.
 
Vonny Sprey
Point England 7 14 eggs, 3 chicks, 0 fledged Problems with pukekos and long grass
 
Shaun Lee
Martins Bay 2 Multiple nests, some hatching, none fledged Some tide affected nests. Human activity may have caused stress for some birds. Alan Seelye


If you have any interesting NZ Dotterel observations you would like to share with the group, please send them through to biodiversity@aucklandcouncil.govt.nz.

I am trying to add further emails to a NZ dotterel warden mailing list. This will mean it is easier to contact you with important updates about NZ dotterels throughout the year. If you know someone who may be interested in signing up, please send this link: http://eepurl.com/1Rdrv

Auckland NZ Dotterel Forum 2015:
Celebration & Inspiration


As I mentioned last month, Auckland Council and Birds NZ ran a forum for the dotterel minders to come together to discuss new management ideas. Our great minute-taker Jeannie Preddey has written up notes on what was discussed at the forum, including contact details of those who spoke, in case there are any questions. Thank you Jeannie. Thanks again to Gwenda, Shaun and Jacinda for their efforts in organising this year's forum.
