I give below the Manchu text and a (clumsy) translation.
han i araha e mo gasha be irgebuhe juwan mudan i irgebun:
Poem in ten rhymes on the cassowary written by the emperor.
te i ere h’alaba i gasha.
tesu bade inu tongga sabumbi.
teike mederi jahūdai deri gajifi.
terei arbun be cohome nirubuhabi:
This bird of Indonesia
is rarely seen in its native country.
Recently it has been brought from a ship
and its picture has been especially painted.
erebe foranggiya ba i niyalma de takabufi.
ere da hūng mederi tun de banjimbi sehe.
erei nirugan leolehe gisun gemu bi.
ejeme arahangge akūmbuha bime getukelehe:
It is said to have been discovered by people from France
and to live on an island of the Da hūng sea.
Here are its image and description.
Record of it has been made complete and it has been explained.
banin nomhon ofi dasihirakū.
ba i halhūn be baime beiguwen de sengguwembi.
banjiha beyei gubci funggaha fulahūri boco bime.
banitai konggolo de fulgiyan sukū tuheme banjihabi:
Quiet by nature, it is no bird of prey.
Seeking heat, it fears cold.
All feathers of its body are deep-red
and its crop is made of red skin at the bottom.
asha de dethe akū ofi deyeme muterakū.
an i arbušacibe uncehen mokto saka.
adarame bahafi ubade isinjiha ni.
aibici baime gajihangge geli waka.
Because its wings have no pinions, it cannot fly.
While it moves normally, the tail is somewhat bald.
How did it manage to come here?
Looking everywhere, no one has brought it. (3)
ume ši lo gasha seme sabi obure.
umesi julge de hafan i hergen obuhakū kai.
udu ferguwecuke gasha obume ujirakū bicibe.
ulabuha manggi inu emu tongga donjin kai:
Do not mistake it for the ši lo bird, taking it as a good omen,
It was not chosen as a rank badge for officials.
Although this marvelous bird cannot be fed,
after it has been handed down, it is indeed a rare thing to hear.

(2) The poem makes use of initial alliteration and final rhymes:
Stanza 2 and 5
Stanza 3 and 4
(3) I am not sure I got this verse right, especially the aibici baime part.
