Rainbow Lorrikette

I live in Corlette Port Stephens NSW And I have noticed there has not been as many Rainbow Lorriketts as they has been in the past I walk along Little Salamander Beach each day and Bagnells Beach as well not much sightings there as well I had a friend from Engadine in the Sutherland Shire and she said the same thing is happening down there as well not as many lorikeets at all Also there has not been as many Red-or Yellow Tailed cockatoos I have only seen six Red -Tailed last week There has been more Corellas around since Christmas And also down at Mambo Creek near Little Salamander Beach there are at least 25 Black Swans that call Mambo Creek home along with six Pelicans Regards Kerry Firkin reff777@bigpond.com.au
