389. Megalurus palustris, Horsf. _The Striated Marsh-Warbler_.

Megalurus palustris, _Horsf., Jerd. B. Ind._ ii, p. 70; _Hume, Rough

Draft N. & E._ no. 440.

Nothing has hitherto been recorded of the nidification of the Striated

Marsh-Warbler, although it has a very wide distribution and is very

common in suitable localities.

The Striated Marsh-Babbler, as Jerdon calls it, has nothing of the

Babbler in it. It rises perpendicularly out of the reeds, sings rather

screechingly while in the air, and descends suddenly. It has much more

of a song than any of the Babblers, a much stronger flight, and its

sudden, upward, towering flight and equally sudden descent are unlike

anything seen amongst the Babblers.

Mr. E.C. Nunn procured the nest and an egg of this species (which

along with the parent birds he kindly forwarded to me) at Hoshungabad

on the 4th May, 1868. The nest was round, composed of dry grass, and

situated in a cluster of reeds between two rocks in the bed of the

Nerbudda. It contained a single fresh egg.

Writing from Wau, in the Pegu District, Mr. Oates remarks:--"I found

a nest on the 19th May containing four eggs recently laid. The female

flew off only at the last moment, when my pony was about to tread on

the tuft of grass she had selected for her home.

"The nest was placed in a small but very dense grass-tuft about a

foot above the ground. It was made entirely of coarse grasses, and

assimilated well with the dry and entangled stems among which it lay.

The nest was very deep and purse-shaped. It was about 8 inches in

total height at the back, and some 2 inches lower in front, the upper

part of the purse being as it were cut off slantingly, and thus

leaving an entrance which was more or less circular. The width is 6½

inches, and the breadth from front to back 4 inches. The interior is

smooth, lined with somewhat finer grass, and measures 4 inches in

depth by 3 inches from side to side, and by 2 inches from front to

back.

"_Megalurus palustris_ is very common throughout the large plains

lying between the Pegu and Sittang Rivers. At the end of May they were

all breeding. The nest is, however, difficult to find, owing to the

vast extent of favourable ground suited to its habits. Every yard of

the land produces a clump of grass likely enough to hold a nest, and

as the female sits still till the nest is actually touched, it becomes

a difficult and laborious task to find the nest."

He subsequently remarks:--"May seems to be the month in which these

birds lay here. The nest is very often placed on the ground under the

shelter of some grass-tuft."

Mr. Cockburn writes to me:--"I found a nest of this bird on the north

bank of the Bramaputra, near Sadija. One of the birds darted off the

nest a foot or two from me in an excited way, which led me to search.

The nest was almost a perfect oval, with a slice taken off at the top

on one side, built in a clump of grass, and only 9 or 10 inches from

the ground. It was made of sarpat-grass, and lined internally with

finer grasses. The grass had a bleached and washed-out appearance,

while the clump was quite green. This was on the 29th May. I noticed

at the same time that the nest was not interwoven with the living

grass. I removed it easily with the hand."

Mr. Cripps says:--"They breed in April and May in the Dibrugarh

district, placing their deep cup-shaped nests in tussocks of grass

wherever it is swampy, in some instances the bottoms of the nests

being wet. Four seems to be the greatest number of eggs in a nest."

The eggs are much the same shape and size as those of _Acrocephalus

stentoreus_. They have a dead-white ground, thickly speckled and

spotted with blackish and purplish brown, and have but a slight gloss;

the speckling, everywhere thick, is generally densest at the large

end, and there chiefly do spots, as big as an ordinary pin's head,

occur. At the large end, besides these specklings, there is a cloudy,

dull, irregular cap, or else isolated patches, of very pale inky

purple, which more or less obscure the ground-colour. In the peculiar

speckly character of the markings these eggs recall doubtless some

specimens of the eggs of the different Bulbuls, but their natural

affinities seem to be with those of the _Acrocephalinae_.

The eggs vary from 0·8 to 0·97 in length, and from 0·61 to 0·69 in

breadth; but the average of twelve eggs is 0·85 by 0·64.
