Stork swarm

“Even the stork in the sky knows her appointed seasons, and the dove, the swift and the thrush faithfully keep their migration patterns. But my people don’t. They are unfamiliar with the judgement of YHWH.”
— Jeremiah 8:7

Thick baobab trees squatted on the edge of the Great Rift Escarpment. They were as ancient and gnarled as the landscape of Tanzania itself. In the distance the sheen of Lake Manyara mingled with the sky. Specks suggestive of birds did the same. I hung out the window of the knobby-tyred truck feeling the wind in my face while Saidi navigated the switchbacks.

I could see why Ernest Hemingway chose to camp here in a forest of fig and mahogany. Eighty years ago he called the region of Lake Manyara "a country to wake up from" and "the loveliest I had seen in Africa."* From this vantage point it was hard to disagree with Papa.

At the base of the escarpment the trees closed ranks. We lost our view to the lake. In its place were other wonders though. Olive Baboons (Papio anubis) scampered (or simply sat) in the roadway. Walkers, bicycles, and enclosed scooters with colorful dongles and other accoutrements appeared as precursors to a town.

"What's the name of this place?"

"Mtowambu."

Saidi, ever economical with his words, didn't flinch when he added "'River of Mosquitos' in English."

I knew we had carried those anti-malarial drugs to the top of Kilimanjaro for a reason.

Needless to say we were not disappointed when the mosquito swarm failed to fall out the sky. But something else did. Something much larger, and, at a glance, more menacing. Swarms of giant storks were suddenly everywhere. They were beyond counting. In the hundreds? For sure. Thousands? Maybe. Some circled slowly overhead, great wings outstretched. Many more rested, nested, and clattered their bills from poo-spangled trees.

For Europeans, the White Stork (Ciconia ciconia) is a good omen. Because this graceful bird devours vermin and prevents fires (or so they say), locals encourage them to build nests on haystacks and telephone poles and rooftops and chimneys. From this proximity, stork behavior is observed and appreciated. They appear as faithful mates and caring parents, attributes that may account for  the their legendary role as deliverers of baby-bundles. 

The Hebrew term khasidah, translated as "stork," springs from one of the most beloved word-families in all the Bible. Khesed is often translated into English as "loyalty," "steadfast love," or "loving-kindness." Obviously, these birds were viewed in a favorable light by others outside of Europe as well!

Migration patterns route them through the Levant from Europe to Africa and back again. This likely explains a handful of appearances of the stork in the Hebrew Bible. They are remembered as birds with seasonal patterns (Jer 8:7), powered by astounding wings (Zech 5:8) and nesters in tall trees (Psalm 104:17). However, they are unclean as a food source (Lev 11:19).

Having belabored the point, only now must I confess that the storks of Mtowambu are not the Ciconia ciconia of European or biblical fame. The crowd on this end of the Great Rift hails from a different genera. The Yellow-billed Stork (Mycteria ibis) has a less heroic travel schedule and more localized habits. Like their cousins, Yellow-bills are large long-legged birds with an appetite. Their color is striking. A white body culminates in a black tail. A long beak is bright yellow, and above that tapered beak is the face, draped in folded red skin.

They do migrate (although we still have much to learn about this). Specialists suggest that the pattern of movement for the Yellow-billed Stork is facultative, that is, they move when they have to, often in response to environmental deterioration. This is different from the White Stork whose migratory pattern is described as obligate, that is to say, it is something they do regularly.**

Yellow-bills are found in wetlands across sub-Saharan Africa. The numbers are particularly high in Kenya and Tanzania.

Our proximity to Lake Manyara accounts for this colony. Freshwater springs rise up in the forest floor (undoubtedly fed by the mountains above the Great Rift Escarpment) and flow into the shallow lake. In the dry season, the waters recede, leaving vast mud flats. These conditions are a bonanza to those who have the tools. The storks feed by wading in marshy areas and stirring the bottom with their feet. At the same time, they drag their open bill in the cloudy water. A keen sense of touch allows them to locate and swallow (in a single gulp!) small fish, frogs, crustaceans, worms, insects and other muck-loving tidbits.

As Saidi drove beneath the trees I looked up cautiously, fingers fiddling with my camera. Nests dangled from thicker branches. Inside these wattle-and-daub constructions was the future of the Yellow-billed Stork. Swarming outside was a cacophonous present.

Life is a mix of the young and ancient in Africa's Great Rift Valley.
