Great plugin

This is a great plugin to display birthday for community buddypress, you need just to add function to load languages in your file loader.php
this the function:

function kechweb_load_textdomain() {
		load_plugin_textdomain( 'bp-birthday-greetings', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
}
add_action( 'plugins_loaded', 'kechweb_load_textdomain' );
