A nightingale has been heard singing in Kensington Gardens (_vide Times_, April 19). A salmon has been seen swimming close to London Bridge. A trout has been observed (reposing on a marble slab) near to Charing Cross. Sticklebacks have been captured in the waters of the Serpentine. Plovers eggs have been discovered in the middle of Covent Garden: I myself have found there as many as two dozen in a single walk. There is a rookery in St. Giles's, well known to the police. I have seen a pigeon shot not far from Shepherd's Bush, and I have heard one has been plucked by a member of the hawk tribe at another West-End haunt. Blackbeetles are common in the back kitchens of Belgravia, and bluebottles abound among the butchers of Whitechapel during the warm months. There is another kind of fly, which is said to be indigenous to the stables of the jobmasters, and which also may be seen by observant Cockney naturalists, but less seldom in Whitechapel than near the Regent's Park. Sparrow-clubs have not been established yet in London, but pea-shooters are common in many of its streets. I am told that early risers may hear a male canary singing in the neighbourhood of Islington at four o'clock, A.M., and may also hear a cock crow any morning, except Sunday, between five and six o'clock. The thrush has been observed among sundry of the children, under medical inspection, in the nurseries and infant hospitals of town. Little ducks are plentiful in the _salons_ of Tyburnia, and in Bayswater and Brompton there are numbers of great geese. Welsh rabbits may be seen close to Covent Garden, and wild turkeys have been noticed even in the Strand, hanging by the beak. In the purlieus of St. Stephen's, where are the sacred haunts of the collective wisdom of the kingdom, I have heard the hootings of many an old owl. From information which I have received from members of the metropolitan police, I may assert that larks are common in the Haymarket, and that on the shores of the silver Thames at Wapping there is frequently observable a goodly flock of mudlarks. From similar information, I may add that there are careful observers in the streets who rarely pass a day without their setting their eyes upon a robbin'. Who shall say that in the very midst of the metropolis there is not abundant evidence of a truly rural, and a tooral-looral life? * * * * * NIGHT-BIRDS THAT MAKE WEST-END NIGHT HIDEOUS.--The 'owls of 'Arry after his larks. * * * * * CHARADE FOR COSTERMONGERS.--My first is unfathomable, my second odoriferous, and my whole is a people of Africa.--_Abyss-inians._ * * * * * CONSOLATION FOR COCKNEYS.--It is all very well to talk of the fine boulevards of Paris; but in the French metropolis, where the rent is so high, and the living so dear, there is not one street to be named with Cheapside. * * * * *
