File "CompleteV2.txt" : Raw data from article "Acoustic cues and season affect mobbing responses in a bird community"
File "AnalysisV3" : R code used for the analyses presented in our article
File "Supplementary Files": 5 additionnal information to complete the article:
			- One additionnal experiment 
			- One additionnal statistical analysis 
			- Information about the playbacks prepared
			- Spectrograms of the mobbing calls of the species we studied 
			- Output of the models that were not selected for the result section because of their higher BIC.
+ 4 examples of the playback stimuli used in this experiment (1CO, 3CO, 1CR, 3CR)


### Experiment ###

The goal of the experiment was to test whether the response of the bird community to mobbing calls
was dependent on two acoustic cues: the number of callers (1 vs 3) and the emitter species (coal versus crested tit)
and whether the different responses could be impacted by season (same experiment done in winter and in spring). 
We created mobbing playbacks of either one coal tit (1CO), three coal tits (3CO), one crested tit (1CR) and three crested tits (3CR)
and launched these playbacks in 100 different points (see the published article for full details). 
If the birds approached in a 10m radius around the loudspeaker and if they produced mobbing calls, they were considered as mobbing. 

### Details for File "Complete.txt": 

- Round: The four playbacks were presented at each of the 100 points but on different days. Round 1 is the first time we went in the field, Round 2 the second time, etc (4 rounds at each season to complete the collection of data).

- Point : ID of each of the 100 points, distanced by at least 100 meters, in the area of the Haut-Bugey (France). 

- Playback : For each treatment, we created five different playbacks (from 1 to E) to avoid pseudoreplication

- TypeTest : Which treatment was launched (1CO, 3CO, 1CR, 3CR)

- Species: The species calling in the playback (Coal or Crested tit)

- Nb Emet: The number of birds calling in the playback (1 vs 3)

- Season : The season in which we tested the birds (spring or winter)

- Nb_TOTAL : the number of birds that mobbed (all species included)

- Nb_Crested_Mob: the number of crested tits that mobbed 

- Nb_Coal_Mob: the number of coal tits that mobbed

- Pres_Total: the presence, or not (dichotomic variable) of at least one bird mobbing 

- Pres_Coal_Mob : the presence, or not (dichotomic variable) of at least one coal tit mobbing 

- Pres_Crested_Mob: the presence, or not (dichotomic variable) of at least one crested tit mobbing
