Where to Get Gifts?
Thought it would be useful to list the levels where gifts are frequently found, especially if the level is easy.
WARNING -- As of 02/12/16, update 2.5.0, it appears that Rovio has totally nerfed farming for present in at least level 9, and possibly all of the 2-room levels. If anyone finds a good level for gifts, please let everyone know.
Updated 9/26/15, but as of 02/12/16 may be useless:
The current table is the number of times a gift appears in the first scene of a 2-scene level. It combines data from everyone who posted up to 9/26/15.

I don't think there are any gifts in the first 7 levels, but I could be wrong. I have not checked to see if the levels with the lower rates in the table above are statistically different than ones with higher rates, and I'm not going to continue collecting data to find out.
Since the 9/14/15 update, there is a >90% probability that the rates in levels 9 and 13 have decreased (based on my data only), and are now at 10 +/- 1%. They were at 14% and 20%, respectively.
As pointed out by @wrw01, since the rates are so low, it is common to get long stretches (20 to 70) attempts without any gifts.
I plan to concentrate statistics on the 2 stage levels; not sure how useful it is to list the rest.
[8/24/15 Update]:
First table combines data from @MVnLA2 @triggerfish @viking @dragonofheart73 @Partshade @achimenes-crataegusmenes. Except where noted, all are 2 scenes.
[Edit 8/29/15]: Table above is for AB2 prior to version 2.1. Frequency of gifts may have changed in update. Table of gifts in other levels deleted.
I have started farming only the first scene in levels 9, 11, 13 and will provide data later.
I have never gotten much of anything in level 8, although others get quite a bit.
[Edit 9/13/15]: Not clear if decline in frequency of gifts is real or just statistical variation. However, I stopped looking in level 11, because I got a really long string of 0 gifts in either scene.
Frequencies of gifts in first scenes of levels 9 and 13 seem to be ~13%. Gifts in both scenes of level 9 is ~22%, but level 13 for both scenes is only ~13%, so not many gifts in second scene.
