SWS1 opsin aa sequences and accession numbers. SWS1 opsin amino acid (aa) sequences from passerine plus falconiform and psittaciform species analysed in the present study and previously. The spectral tuning aa sites 86, 90 and 93 (see text) are marked in bold, as are the ENA accession number of sequences new to this study. Type of SWS1 opsin is estimated from the tuning sites as either VS (violet sensitive) or UVS (UV-sensitive). The taxonomy follows the IOC World Bird List [69]. Numbers after species names signify the number of individuals sequenced. Information on geographic location for the new samples is available at ENA http://www.ebi.ac.uk/ena/data/view webcite/< ACCESSION NUMBERS HE601811-HE601869 >.

Alternative recontruction of SWS1 opsin evolution, 1. Same tree as in Figure 2, but with clades b and c, which are reconstructed with low support, collapsed, and Cnemophilus placed as sister to the 'core Corvoidea' clade. VS/UVS optimisation represented by yellow for VS, blue for UVS, and barred for ambiguous.

Alternative recontruction of SWS1 opsin evolution, 2. Same tree as in Figure 2, but with all 'basal' nodes with posterior probability < 0.95 collapsed. VS/UVS optimisation represented by yellow for VS, blue for UVS, and barred for ambiguous.
