4702 Tue ZooLtoctst—NoveEMBER, 1875. 
of which he was unacquainted; we during that day, being on the 
look-out for him, saw the bird without being able to get a shot at 
him: the bird was, Iam confident, a Richardson’s skua. Next 
day, on going to the beach, we saw several Richardson’s, and 
amongst them three or four pomarines. We succeeded in shooting 
a good many of the former, but it was not until the 27th that we 
got within shot of one of the latter, which my brother shot: it 
was a male pomarine, in the black plumage. The flight of skuas 
remained about our harbour for several days—I may say whilst the 
heavy weather lasted: on the weather moderating a little they all 
disappeared. I may mention that while the two species of skuas 
which I have mentioned remained, I also observed one of the 
common skuas (Z. catarrhacles).” 
The next occasion on which | had the pleasure of seeing skuas 
passing was on the 18th of September, 1869. It was a fine, bright, 
calm day: [was in one of my fields looking at the reapers at work, 
when, chancing to look upwards, my attention was drawn to a flock 
of fifteen skuas passing at an immense height on their old course 
to south-west. If the day had not been so clear I could not have 
recognised them as skuas, as I was only just enabled to make out 
their long tails against the blue sky, they kept at such a height. 
It is most probable that the great flight had passed on before, and 
that I only chanced to see the last of the flocks. 
Again, on the 3rd of October, 1874, I was fortunate in witnessing 
a small flight, or part of a flight, of skuas migrating in the usual 
direction. ‘The weather had been very stormy, with heavy showers, 
for some days before; wind north-west on this day, when, about 
ten o’clock, I observed a flock of about twenty birds flying up the 
river from the sea; a short time afterwards four birds passed ; then 
a litle flock of three, which were followed by four, and in about a 
quarter of an hour a solitary bird (which I think was a pomarine) 
brought up the rear, and, as far as I saw, ended the flight for the 
day. 
I may conclude these notes by giving the dates of the occurrence 
of solitary birds unconnected with the flights already mentioned, 
but probably stragglers from migratory flights passing unnoticed 
at the time. 
On the 29th of September, 1855, I shot an immature specimen 
of L. Richardsonii near the island of Bartra; and sometime in the 
month of September, 1858, I obtained another Richardson’s skua,
