Hi Steemians... A few days ago, I created a contest to guess the name of the bird, but I see only a few people who participate, Maybe this is because:
- Lazy to find out.
- Think of it as unnecessary.
- It's not my field.
- Or even lazy to read...馃槤
Okey.... The name of this bird is Red-footed Falcon,(Falco vespertinus), this is a rare species of Falconidae family. The population of birds is currently declining, and in August 2004 a red-footed falcon was found in North America for the first time on the island of Martha's Vineyard, Massachusetts.
And by 2015, I found this bird in the forest, about 10 kilometers from my hometown, in Tutut Forest.

I am grateful to some people who have participated in this contest, 
This is a comment @ steemwart, which became a new lesson for me.
Due to this challenge, I have left my work today for three hours, only to find the source and name of the bird species you contesting.
You make me read a lot, unpack various libraries online from several countries. But I also do not get the right name for this type of bird.
I will offer with "Peregrine Falcon (Falco peregrinus ernesti)".
This bird is found in several archipelago archipelago, including Sumatera that is in Aceh.
The following is the distribution of Falco peregrinus ernesti I quoted from https://en.wikipedia.org/wiki/Peregrine_falcon.
Hopefully I'm not wrong, thanks @ magh.
And now I will continue my work, completing the monthly report that I have ignored since this morning.
You can read more about Red-footed Falcon in the quotation below, or go directly to the link Wikipedia
The red-footed falcon (Falco vespertinus), formerly western red-footed falcon, is a bird of prey. It belongs to the family Falconidae, the falcons. This bird is found in eastern Europe and Asia although its numbers are dwindling rapidly due to habitat loss and hunting. It is migratory, wintering in Africa. It is a regular wanderer to western Europe, and in August 2004 a red-footed falcon was found in North America for the first time on the island of Martha's Vineyard, Massachusetts
I will make another contest in the future, do not look at the gift I give, but remember that, science is everything.
