Avian biodiversity is declining across the country, and conservation lands alone will likely not be able to support vibrant avian communities long-term. Agricultural expansion contributes to this bird population decline, but the integration of bird friendly practices into agricultural land, such as vineyards, could support many birds that have lost habitat to development. We assessed how different habitat characteristics of existing vineyards in San Luis Obispo County, California, including percent grassland, shrubland, vineyard, agriculture, and canopy cover, as well as structural complexity, influence taxonomic and functional avian community structure as well as individual species occupancy. Variation in canopy cover and shrubland cover appeared to have the greatest influence on community composition in and around the vineyards. Whereas canopy cover, structural complexity, and proximity to streams influenced many species’ occupancy. Vineyard modifications such as adding small amounts of canopy and preserving existing natural habitat could have large impacts on bird communities in vineyards.  This analysis will help guide local bird friendly vineyard management to help increase the abundance and diversity of birds that can utilize these modified lands for foraging, shelter, and to connect larger areas of protected land.
