However, a single, replicated study in forests in Spain in 2004 (Remacha et al. 2011) found that fewer birds, but not fewer species, were observed as visitor number increased. This effect was largely due to decreases in collared dove Streptopelia decaocto presence and serin Serinus serinus abundance. Remacha, C., Perez-Tris, J. & Antonio Delgado, J.
