Bird abundance and distribution data for emergency response.

Tracking data

  • Get metadata
  • Build kernels 2 usage grid function

Abundance data

  • Get metadata
  • Kernels vs. rqss GAMs

##PROS and CONS of different methods

###GAMs

PROS

  • Easily interpretable value (group size; number of birds seen when going to a site, by quantiles)

  • Independent of the number of observers/checklists (but needs a certain number of observations to give a meaningful result)

CONS

  • Can be difficult to implement

  • Sensible to smoothing value

  • May give extreme results when few observations are available and quantile is high (e.g. 90%)

  • Need cells for predictions

###KERNELS

PROS

  • Easier to implement and to use (e.g. risk: high, medium, low)

  • Easy to output to polygons

CONS

  • Not easy to interpret real meaning (group size, number of birds concerned?)

  • Strongly depends on the amount of observers and checklists (lightly mitigated by a weigthing method based on numbers)

  • Sensible to bandwith value and different parameters

##NOTES and IDEAS

  • Use GAMs to predict quantile group size in each kernel polygons

  • Need to sum species by groups when doing GAMs

  • Integrate ECSAS, tracking and ebird data within the same kernel output

##TODO

  • Winter Eiders, check email for using whites and adding browns which are in % ?
  • Take out groups and observations flagged red in FB dynamic excel file (in downloads)
  • Add EPOQ data, but only what is older than 2012 (?) to reduce overlap with EBIRD data
  • Verify which seasons to use
  • Add data from SOMEC (2012 and over ?) to the ECSAS data
  • Use 50-70-90% kernels
  • Shanti wants tracking data? (email 01-27)
  • BIOMQ never was included in the kernel output (email 01-27)
  • Adjust seasons according to (email 01-27)
  • Check list of things left to do on google drive
  • Make sure last version of ECSASconnect is used to produce RData with ECSAS data
  • Check FB commentary on putting seabird survey data with ECSAS and shorebird data with ebird
