African Hornbills

I checked my stamp album, and I found these two beautiful postally used hornbill stamps of African countries. The stamp of Malawi depicts a silvery cheeked hornbill. This K2 stamp was issued on 25 July, 1988 as one of the 15 denominations of a set of definitive stamps. The second stamp is from Kenya depicting yellow billed hornbill. The 50s stamp was issued on 22 February, 1993 as one of the 11 denominations of a set of definitive stamps. The two hornbill species are confined to continent of Africa.
