Early in my travels to the Middle East I learned about the migration of the stork. They spend the winters in south-east Africa and then follow the great rift or depression through Israel, some going east to Asia and others going west to Europe. In the fall of the year they make their way back to Africa.
If you have traveled from Tiberias to Jericho by way of the Jordan valley you know that the valley is sometimes far below the highway. Once I saw a flock of storks traveling north through the valley. The stork, and other birds, spend some time in the Hulah valley north of the Sea of Galilee before continuing their trek.
Jeremiah seems to be describing the migratory habits of the stork.
Even the stork in the heavens knows her times, and the turtledove, swallow, and crane keep the time of their coming, but my people know not the rules of the LORD. (Jeremiah 8:7 ESV)
I have seen many storks in Turkey. They make their nests on chimneys (has to be summer!), on power poles, and on old columns. The Psalmist indicates that they also nest in the fir trees (Psalm 104:17). Our photo today was made near an old Roman road at Kovanlik, Turkey. It’s almost like they know to follow the roads through Asia to Europe.
According to the Mosaic law the stork was an unclean bird (Leviticus 11:19; Deuteronomy 14:18). The prophet Zechariah uses the movement of the storks with their strong wings as an illustration (which I dare not try to interpret).
Then I lifted my eyes and saw, and behold, two women coming forward! The wind was in their wings. They had wings like the wings of a stork, and they lifted up the basket between earth and heaven. (Zechariah 5:9 ESV)
The Keren Kayemeth Leisrael JNF website provides good information about storks, and other birds, in the Hulah valley here. Here is another nice site with information about storks and some good photos.
