In the olden times, no artificial means of measuring time were known, and the devout Jew was consequently fearful lest he might unwittingly break the law by doing on one day an act which ought to have been done on another. A convenient method for ascertaining the time was, however, employed, and, as soon as the Ravens, rooks, and similar birds were seen returning to their homes, the sun was supposed to be setting.
This habit of returning regularly at the same time is mentioned by Mr. Tristram in his "Land of Israel:"—
"Of all the birds of Jerusalem, the raven is decidedly the most characteristic and conspicuous. It is present everywhere to eye and ear, and the odours that float around remind us of its use. On the evening of our arrival we were perplexed by a call-note, quite new to us, mingling with the old familiar croak, and soon ascertained that there must be a second species of raven along with the common Corvus corax. This was the African species (Corvus umbrinus, Hed.), the ashy-necked raven, a little smaller than the world-wide raven, and here more abundant in individuals.
"Beside these, the rook (Corvus agricola, Trist.), the common grey, or hooded crow (Corvus cornix, L.), and the jackdaw (Corvus monedula, L.), roost by hundreds in the sanctuary. We used to watch them in long lines passing over our tents every morning at daybreak, and returning in the evening, the rooks in solid phalanx leading the way, and the ravens in loose order bringing up the rear, generally far out of shot. Before retiring for the night, popular assemblies of the most uproarious character were held together in the trees of the Kedron and Mount Olivet, and not until sunset did they withdraw in silence, mingled indiscriminately, to their roosting-places on the walls.
"My companions were very anxious to obtain specimens of these Jerusalem birds, which could only be approached as they settled for the night; but we were warned by the Consul that shooting them so close to the mosque might be deemed a sacrilege by the Moslems, and provoke an attack by the guardians of the Haram and the boys of the neighbourhood. They finally determined, nevertheless, to run the risk; and stationing themselves just before sunset in convenient hiding-places near the walls, at a given signal they fired simultaneously, and, hastily gathering up the spoils, had retreated out of reach, and were hurrying to the tents before an alarm could be raised. The discharge of ten barrels had obtained fourteen specimens, comprising five species.
"The same manœuvre was repeated with equal success on another evening; but on the third occasion the ravens had learned wisdom by experience, and, sweeping round Siloam, chose another route to their dormitory."
Those who have tried to come within gunshot of a Raven, even in this country, can appreciate this anecdote, and can understand how the Raven would ever afterwards keep clear of a spot where the flash and smoke of fire-arms had twice appeared.
An anecdote which authenticates this cautious turn of mind in the Raven is given in Mr. Thompson's work on the "Natural History of Ireland." There was a large yard in which the sparrows used to congregate, and it was a custom of the owner to lay a train of corn for the sparrows to eat, and then to rake the whole line with a discharge from a gun concealed in an outhouse. A tame Raven lived about the premises, and as soon as it saw any one carrying a gun towards the fatal outhouse, it became much alarmed, and hurried off to hide itself. As soon as the gun was fired, out came the Raven from its place of concealment, pounced on one of the dead sparrows, carried it off, and ate it in its private haunt.
The nest to which the Raven returns with such punctuality is placed in some spot where it is safe from ordinary intruders. The tops of lofty trees are favoured localities for the nest, and so are old towers, the interior of caves, and clefts in lofty precipices. The nest is large and clumsy, and the bird, trusting in the inaccessible character of the locality, troubles itself very little about concealment. The Raven is a peculiarly domestic bird, and a pattern of conjugal affection. It pairs for life, and both male and female take their share of sitting on the eggs and nurturing the young.
