Beach Nesting Birds





BirdLife Australia’s Beach-nesting Birds project has been operating with community volunteers across Australia since 2006 to attain the following:

Raise awareness among beach users concerning beach-nesting birds
Train native volunteers to watch beach-nesting birds, establish threats and improve management Protect eggs and chicks through temporary fencing, signage, artificial shelters Research new ways in which of protective birds and rising breeding success

What area unit beach-nesting birds?

Many different sorts of birds sleep in Australia’s coastal areas - gulls, terns, cormorants and shorebirds, to call one or two - however solely a couple of of them really nest on the beach.

There area unit 5 species of Australian shorebirds that nest solely or typically on the beach:

• Pied limicoline bird
• Sooty limicoline bird
• Beach Stone-curlew
• Red-capped shore bird
• Hooded shore bird

"Because beach-nesting birds have such poor breeding success, their numbers are a unit declining and it will not be long before they become extinct. They're in desperate would like of a serving to hand"

We tend to think about beaches being lined with clean white sand, however not all beaches area units sanding. Beach-nesting birds carry on many various sorts of beaches. Jet Oystercatchers like rocky coasts, wherever they seek for food among the rocks. Multicolored Oystercatchers are a unit additional possible to be seen on sandy beaches wherever their area unit a couple of rocks concerning yet. Beach Stone-curlews typically carry on secure beaches with muddy sand and mangroves growing near . Red-capped Plovers are a unit typically seen on secure muddy shores, however they conjointly occur on sandy ones, and area unit galore around wetlands, each saline and fresh.
Hooded Plovers (in their gap range) solely occur on sandy beaches that area unit exposed to the ocean swells and backed by sand dunes; in fact, these beaches are a unit wherever the majority favor to go. Beach-nesting birds, as well as Hooded Plovers, lay their eggs directly on the sand during an easy, shallow nest scrape. The nest is anyplace higher than the high-tide mark, on the beach or within the dunes. Another beach-nesting species, notably Oystercatchers, may nest in rocky areas and on offshore islands. In Australian state, they conjointly nest inland around salt lakes and so have a special set of threats.



The reason are beach-nesting birds insecure?

The greatest danger to Australia’s beach-nesting birds are usually agitation through individuals traveling to the seashore. This agitation is usually best throughout spy and also summer time, when beach-nesting birds commonly set their own eggs, coinciding while using the optimum amount of recreational by using beach locations.

Hooded Plovers would be the many insecure ones just about all, when they would be the birds which usually inhabit the beach locations the majority of people prefer to check out. Their particular eggs are smaller (about how big some sort of 20-cent piece) and intensely nicely camouflaged, in order that they are easily trodden with by chance. When the incubating older is usually terrified from the home through passers-by, the eggs might actually cook inside the sunshine, or turn out to be way too cool inside the trendy weather conditions; no matter what, this eliminates the chick building inside the egg cell, and also the egg cell will not likely hatch. Similarly, when individuals bother some sort of fluffy chick, this rapidly incurs the crushed stone sand hills and also hides. As it is usually running, the chick can burn precious electricity, buying enough it's disappearing this cannot give food to (they commonly forage for the water’s edge), to ensure that some sort of chick that may be compelled to own and also held throughout the day can very easily deny your body food.
