From: Daily activity budgets reveal a quasi-flightless stage during non-breeding in Hawaiian albatrosses

Model # Response Model term df F P-value
1. Sustained flight, >0 s(DSD):sp(LAAL) 6.78 12.82 < 0.0001
   s(DSD):sp(BFAL) 3.88 39.97 < 0.0001
   Non-breeding Phase 2 9.86 < 0.0001
   Species 2 15.98 < 0.0001
   Phase:Species 2 4.01 0.0181
2. Sustained flight (0,1) s(DSD) 4.50 23.73 < 0.0001
   Non-breeding Phase 2 10.07 < 0.0001
3. Floating s(DSD) 5.78 16.83 < 0.0001
   Non-breeding Phase 2 11.26 < 0.0001
4. Foraging s(DSD):sp(LAAL) 3.12 7.67 < 0.0001

   Non-breeding Phase 2 6.55 0.0014
  1. Degrees of freedom for the smoothers are taken from the model hat matrix. Proportion of time spent daily in sustained flight was zero-inflated (>35% zeros) and thus was modelled in two parts as a hurdle model with both quasi-binomial and binary distributions (Models 1 and 2).
