The strip of grass panties ( Amytornis striatus ) is a occurring in Australia songbird from the family of the Wrens (Maluridae).
features
Striped grass hatchers reach a body length of 14.5 to 19.0 centimeters and a weight of 15.0 to 23.0 grams. There is no significant sexual dimorphism between the sexes in terms of plumage color . The basic color is brownish, but its intensity varies greatly from region to region. The head and cloak plumage are streaked with white lines. The throat is whitish, the chest light gray. A black beard stripe and a red-brown stripe over the eyes are noticeable . The long control springs are brown. In the females, the lateral breast area is slightly rust-red in color. The beak is dark gray in both sexes, the iris dark brown, legs and feet are gray brown.
Distribution, subspecies and habitat
The striped grass hatchers occur exclusively on the Australian continent. In addition to the south of Australia, in New South Wales and the north west of Victoria occurring nominate Malurus striatus striatus two more subspecies known:
- Amytornis striatus rowleyi Schodde & Mason , 1999, in the middle of Queensland
- Amytornis striatus whitei Mathews , 1910, in Western Australia
The individuals that occur in the Northern Territory and are known as Amytornis striatus oweni are now included in the nominate form. A comparison of the aforementioned subspecies revealed genetic differences that opened up the possibility that they could be species in their own right. However, due to the great morphological and ecological similarity of the individuals, this cannot yet be conclusively confirmed. Further research on this subject is required.
The main habitat of the species are areas overgrown with prickly head grasses ( Triodia ), areas rich in shrubbery, sandy or rocky areas, and light eucalyptus forests .
Way of life
The birds feed on insects, for example ants (Formicidae) or beetles (Coleoptera) as well as the seeds of spiked grass. The food is usually looked for individually or in small groups on the ground. The main breeding season falls from August to January, but can vary depending on the rainy season. Usually several broods are carried out per year. Striped grass hatchers mostly live in pairs. The females make the nest on their own. It has a closed oval shape, has a side entrance hole in the upper area, is made of dry blades of grass and strips of bark and lined with fine grass. As a rule, it is laid out in tufts of prickly grass and provided with two to three eggs that are hatched in 14 days. The nestling period is also 14 days. Both parents provide the boys with food and stay with the family for some time after they leave.
Danger
The striped grass hatchers are widespread in their areas of occurrence and are therefore classified as 
“ least concern” by the World Conservation Organization ( IUCN ). Due to the reclamation of some habitats, the nominate form is on the decline, but has not yet reached the level of endangerment.
