the

Why are Starlings an Invasive Species Where Introduced 2018

I'm here to tell you about the negative

effects starlings have on our native

birds here in North America and

elsewhere let's watch the video and find

out more you so what is this darling

well the Starling is an old-world

songbird also known as the common

Starling or European Starling it is

native of Europe northern Africa and

Southwest Asia starlings are a cavity

nesting bird and will nest in almost any

cavity that they can find they

especially are attracted to holes in

buildings and other man-made structures

they also like to nest in woodpecker

holes and nest boxes so how do you

identify starlings

as you can see starlings are dart chunky

birds they're about eight and a half

inches long with a long pointed bill

when flying you'll note their short

square tail and triangular wings in the

winter their bill is black and their

body is covered with white spots by

spring their bill turns yellow and they

lose their spots breeding birds are an

iridescent purple and green juvenile

starlings are a drab grayish brown as

they molt they will attain dark feathers

with white spots like an adult

although starlings can look black in

color and associate with black birds

they are not members of the new world

black bird family the old-world Starling

family is their lineage why are

starlings an invasive species where

they've been introduced

well starlings have been introduced in

North America Australia New Zealand

South Africa Argentina and elsewhere

where they are introduced they often

out-compete native cavity nesting birds

they reproduce quickly and spread

aggressively they are not a protected

species in North America where they can

be legally eliminated wherever they are

introduced they are not protected and

you can legally remove their nest eggs

and young in comparison native birds are

protected and you cannot harm them or

their nests

so how did they out-compete native

cavity nesting birds starlings are very

aggressive and persistent and are almost

always successful at evicting other

birds from their nesting cavities

the Starling population is so large that

they outnumber native cavity nesting

birds the native birds are relatively

defenseless against the starlings as

they did not evolve together I've even

witnessed starlings attacking each other

while fighting for a nesting site

woodpeckers are especially vulnerable to

starlings the starlings will wait for

woodpeckers to excavate a cavity and

then attack the woodpeckers until the

woodpeckers finally give up when if

Starling chooses a cavity to use they

will destroy the eggs the young and even

the adults of the native birds using the

cavity they use their long pointed bill

the stab and injure or even kill their

competition once the site is acquired

they may build a nest on top of existing

eggs or young they begin nesting before

migrants are arrived on their breeding

grounds and hence prevent them from

nesting successfully they're able to

evict birds as large as wood ducks from

their nests they can also evict kestrels

owls fly catchers and purple martins so

how can you control starlings I find

trapping starlings to be the best method

of controlling their numbers so that

native birds can nest successfully when

you remove a pair of starlings from the

population you are also removing their

offspring from the population with

starlings producing two broods of five

each that is two parents and ten

offspring that will not compete with

native birds if you provide nest boxes

for Flicker woodpeckers you have to trap

the starlings to prevent them from

evicting the woodpeckers so what effect

do starlings have on native birds well

every time a pair of starlings prevent a

pair of native birds from nesting they

reduce the native bird population and

increase the Starling population if

native birds aren't raising young their

population will continue to fall sternly

it's like the nest in the open the same

habitat

reference of Flickr and red-headed

woodpeckers these two species are both

in decline and I believe starlings are

the main reason why according to the

North American breeding bird survey

northern flickers numbers have decreased

about fifty percent since the mid 1960s

while redheaded woodpeckers have

declined 70 percent since that time so

let me share some of my experiences I've

witnessed starlings destroying eggs

killing the young and fighting with

adult flicker woodpeckers stabbing the

defenseless flickers with their bill I

trap and eliminate between 100 and 400

starlings a year in my yard using baited

and nest box traps imagine a pair of

woodpeckers defending against that many

starlings since I began trapping

starlings the flickr woodpeckers are

able to nest successfully every year in

my yard in 2017 I had three pairs nest

here great crested fly catchers are able

to nest every year in my yard as well

because I control starlings on the farm

red-headed woodpeckers have nested

successfully in a nest box as well as

wood ducks and multiple pairs of

flippers you live in a location where

starlings have been introduced what bird

species do they compete with where you

live do you control their population
