Yesterday I posted about toxic and poisonous plants and household products for birds. Today I want to post about safe plants for birds. Please have a read through these websites:
Index of plants considered safe for birds and/or other pets
Safe Plants and Trees for Aviary Birds
Toxic and Safe Plants/Trees for Birds (this one has both toxic and non-toxic plants listed)
