As it flew at him, swooping down, its black, horribly alive eyes fixed on him, Mike cut sharply right. The bird missed him — barely. The dusty smell of its wings was overpowering, unbearable.

Now he was running parallel to the fallen smokestack, its tiles blurring by. He could see where it ended. If he could reach the end and buttonhook to the left, get inside, he might be safe. He thought the bird was too big to squeeze inside. He came very close to not making it. The bird flew at him again, pulling up as it closed in, its wings flapping and pushing air in a hurricane, its scaly talons now angled toward him and descending. It screamed again, and this time Mike thought he heard triumph in its voice.

He lowered his head, put his arm up, and rammed straight of rward. The talons closed and for a moment the bird had him by the forearm. The grip was like the clutch of incredibly strong fingers tipped with tough nails. They bit like teeth. The bird's flapping wings were a thunder in his ears; he was dimly aware of feathers falling around him, some brushing past his cheeks like phantom kisses. The bird rose then, and for just a moment Mike felt himself pulled upward, first straight, then on tiptoe . . . and for one freezing second he felt the toes of his Keds lose contact with the earth.

'Let me GO!' he screamed at it, and twisted his arm. For a moment the talons held on, and then the sleeve of his shirt ripped. He thumped back down. The bird squalled. Mike ran again, brushing through the thing's tailfeathers, gagging at that dry smell. It was like running through a shower-curtain of feathers.

Still coughing, eyes stinging from both tears and whatever vile dust coated the bird's feathers, he stumbled into the fallen smokestack. There was no thought now of what might be lurking inside. He ran into the darkness, his gasping sobs taking on a flat echo. He went back perhaps twenty feet and then turned toward the bright circle of daylight. His chest was rising and falling in quick jerks. He was suddenly aware that, if he had mis judged either the size of the bird or the size of the smokestack's muzzle, he had killed himself as surely as if he had put his father's shotgun to his head and pulled the trigger. There was no way out. This wasn't just a pipe; it was a blind alley. The other end of the stack was buried in the earth.

The bird squalled again, and suddenly the light at the end of the smokestack was blotted out as it lighted on the ground outside. He could see its yellow scaly legs, each as thick as a man's cab's. Then it cocked its head down and looked inside. Mike found himself again staring into those hideously bright fresh-tar eyes with their gold wedding-rings of iris. The bird's beak opened and closed, opened and closed, and each time it snapped shut he heard an audible click, like the sound you hear in your own ears when you snap your teeth together hard. Sharp, he thought. Its beak is sharp. I guess I knew birds had sharp beaks, but I never really thought about it until now.

It squawked again. The sound was so loud in the tile throat of the stack that Mike clapped his hands to his ears.

The bird began to force itself into the mouth of the stack.

'No!' Mike cried. 'No, you can't!'

The light faded as more of the bird's body pressed its way into the stack's bore (Oh myLord, why didn't I remember it was mostly feathers? Why didn't I remember it could squeeze?). The light faded . . . faded . . . was gone. Now there was only an inky blackness, the suffocating attic –smell of the bird, and the rustling sound of its feathers.

Mike fell on his knees and began to grope on the curved floor of the smokestack, his hands spread wide, feeling. He found a piece of broken tile, its sharp edges furred with what felt like moss. He cocked his arm back and pegged it. There was a thump. The bird uttered its buzzing, chirruping sound again.

'Get out of here!' Mike screamed.

There was silence . . . and then that crackly, rustling sound began again as the bird resumed forcing itself into the pipe. Mike felt along the floor, found other pieces of tile, and began to throw one after another. They thumped and thudded off the bird and then clinked to the tile sleeve of the smokestack.

Please, God, Mike thought incoherently. Please God, phase God, please God —

It came to him that he ought to retreat down the smokestack's bore. He had run in through, what had been the stack's base; it stood to reason that it would narrow as he backed up. He could retreat, yes, and listen to that low dusty rustle as the bird worked its way in after him. He could retreat, and if he was lucky he might get beyond the point where the bird could continue to advance.

But what if the bird got stuck?

If that happened, he and the bird would die in here together. They would die in here together and rot in here together. In the dark.

'Please, God!' he screamed, and was totally unaware that he had cried out aloud. He threw another piece of tile, and this time his throw was more powerful — he felt, he told the others m u c h l a ter, as if someone were behind him at that moment, and that someone had given his arm a tremendous push. This time there was no feathery thud; instead there was a splatting sound, the sound a kid's hand might make slapping into the surface of a bowl of half-solidified Jell-O. This time the bird screamed not in anger but in real pain. The tenebrous whirr of its wings filled the smokestack; stinking air streamed past Mike in a hurricane, flapping his clothes, making him cough and gag and retreat as dust and moss flew.

Light appeared again, gray and weak at first, then brightening and shifting as the bird retreated from the stack's muzzle. Mike burst into tears, fell to his knees again, and began grubbing madly for more pieces of tile. Without any conscious thought, he ran forward with both hands full of tiling (in this light he could see the pieces were splotched with blue – g r a y moss and lichen, like the surface of slate gravestones), until he was nearly at the mouth of the stack. He intended to keep the bird from coming back in if he could.

It bent down, cocking its head the way a trained bird on a perch will sometimes cock its head, and Mike saw where his last shot had struck home. The bird's right eye was nearly gone. Instead of that glittering bubble of fresh tar, there was a crater filled with blood. Whitish-gray goo dripped from the corner of the socket and trickled along the side of the bird's beak. Tiny parasites wriggled and squirmed in this pussy discharge.

It saw him and lunged forward. Mike began to throw chunks of tile at it. They struck its head and beak. It withdrew for a moment and then lunged again, beak opening, revealing that pink lining again, revealing something else that caused Mike to freeze for a moment, his own mouth dropping open. The bird's tongue was silver, its surface as crazy-cracked as the surface of a volcanic land which has first baked and then slagged off.

And on this tongue, like weird tumbleweeds that had taken temporary root there, were a number of orange puffs.

Mike threw the last of his tiles directly into that gaping maw and the bird withdrew again, screaming its frustration, rage, and pain. For a moment Mike could see its reptilian talons . . . Then its wings ruffled the air and it was gone.

A moment later he lifted his face — a face that was gray-brown under the dirt, dust, and bits of moss that the bird's wind-machine wings had blown at him — toward the clicking sound of its talons on the tile. The only clean places on Mike's face were the tracks that had been washed clean by his tears.

The bird walked back and forth overhead: Tak-tak-tak –tak.

Mike retreated a bit, gathered up more chunks of tile, and heaped them as close to the mouth of the stack as he dared. If the thing came back, he wanted to be able to fire at it from point –blank range. The light outside was still bright — now that it was May, it wouldn't get dark for a long time yet — but suppose the bird just decided to wait?
