Mysql – How to pivot to summarize the entries by a specific area

I have a map where every row represents a bird and a row with the attributes shown in the excerpt of the attribute table:

round     | area | date         | species     | behaviour
---------------------------------------------------------
1         | 20   | 2018-04-13   | woodpecker  | NULL
1         | 55   | 2018-04-14   | woodpecker  | NULL
1         | 21   | 2018-06-01   | robin       | NULL
1         | 55   | 2018-04-14   | blackbird   | NULL
1         | 55   | 2018-04-14   | blackbird   | NULL
1         | 55   | 2018-04-14   | robin       | NULL
2         | 55   | 2018-05-28   | chaffinch   | NULL
2         | 20   | 2018-05-29   | chaffinch   | NULL
3         | 21   | 2018-06-01   | robin       | breedig
3         | 55   | 2018-06-01   | blackbird   | NULL

Every study area was visited n-times (see column "round", where "round" is global. That means, that when we did not
find a single bird on a specific round, we have no entry for this area on this date but the round will increase next time the area is visited)

What I need is a table like that one below. I have no idea, how to get this done with SQL. What I need is something like:

*Start with lowest round
    get area and count the species for this area
    next area
next round*

The wanted table:

area  | round | date        | woodpecker | robin | blackbird | chaffinch | sum
--------------------------------------------------------------------------------
20    | 1     | 2018-04-13  | 1          | 0     | 0         | 0         | 1
55    | 1     | 2018-04-14  | 1          | 1     | 2         | 0         | 4
21    | 1     | 2018-04-01  | 0          | 1     | 0         | 0         | 1
20    | 2     | 2018-05-29  | 0          | 0     | 0         | 1         | 1
55    | 2     | 2018-05-28  | 0          | 0     | 0         | 1         | 1
21    | 3     | 2018-05-28  | 0          | 1     | 0         | 0         | 1
55    | 3     | 2018-06-01  | 0          | 0     | 1         | 0         | 1
