Good to see you cover a place not so well known in the other parts of the country..Thanks.
The sarus-cane that you mention is the purple-heron, the first of your raptors is the shikra..other birds i could make out are..heron,common moorhen,purple swamphen,egrets,lapwing,and ducks..
This place might be equally interesting during the 'post-winter' months...like march onwards..might be hot but you will certainly be able to find the local birds in the vegetation.
Regards.
