3. bird_ID: unique identity of the bird
4. exper: treated nest (t), control nest (c)
5. bird_tr: bird was treated (y), assigned as treated (in case of control nests; y) or untreated (n) or assigned as untreated (n)
6. treat: type of incubation bout: before treatment = 1b, treated (heated) = 2t, after treatment = 3a
7. int: explicitly coded interaction of exper:bird_tr:treat
8. bout_length: length of incubation bout in minutes
9. bout_length_b: left centered length of incubation bout in minutes; mean before incubation bout of the individual was subtracted from all its incubation bouts
10. inc_eff: constancy incubation bouts
11. inc_start: date and time when the birds at a given nest initiated the incubation
12. inc_start_j: a day within the breeding season when the birds at a given nest initiated the incubation (1 is June 1, 2011)
13. bout_start: date and time when the incubation bout started
14. bout_start_j: a day of incubation, within which the incubation bout started (1 is the first day of incubation in a given nest)
15. bout_start_s: a day of breeding season, within which the incubation bout started (1 is June 1, 2000)
16. time: time when the incubation bout started
17. rad: radians of time
18. dist_b: disturbance during incubation bout (yes = 1, no = 0)
19. longit: longitude coordinate of the nest location
20. latit: latitude coordinate of the nest location
21. n: order of the bout within the nest (1 = 1st bout included in the analyses within the nest)

--------------------------------------------------------------------------------------------------------

B) Cresswell_et_al_2003_data.txt
-- contains data used in the insulation experiment models
1. pairs: unique identity of the nest pair within matched-pair cross-over experimental design
2. nest: unique identity of the nest
3. sex: sex of the bird (f = female, m = male)
4. order: was the treatment applied in the first 48h of experiment (TC) or in the second 48h period (CT)
5. exp: type of incubation bout: control = c, treated (insulated) = t, insulation was inserted or taken away = 2
6. period: first or second 48h period of the experiment
7. comp: was the bout complete (yes = 1, no = 0); incomplete bouts = bouts were system failed or within which birds prematurely ended the incubation due to disturbance - work at other nests
8. bout_length: length of incubation bout in minutes
9. bout_start: date and time when incubation bout started
10. bout_start_s: a day of breeding season, within which the incubation bout started (1 is June 1, 2000)
