  Trees for Life - Species profile: Scottish crossbill
All three species are identical in plumage, and the Scottish crossbill is intermediate in physical size between the smaller common crossbill and the larger parrot crossbill.
The Scottish crossbill is confined to the Highlands of Scotland, where it occurs in the pinewood remnants of the Caledonian Forest, and in conifer plantations which are 100 years or older in age.
The crossbill feeds on pine seeds either by pulling a cone off a branch and then holding it with its feet while it uses its bill to extract the seeds, or it acrobatically moves around the cone, extracting the seeds without removing the cone from the branch.

 Common Crossbill, Loxia curvirostra
Crossbills are thirsty birds-doubtless on account of their diet of pine seeds-and these rarities have been watched drinking at carpark puddles.
In parts of their range, crossbills breed in every month of the year, their ability to withstand a cold climate enabling them to breed whenever there is a good cone crop.
It will be most interesting to record the numbers of crossbills remaining to breed in the Breckland Forest rather than returning to the dark and distant fir forests of Scandinavia.

 Scottish crossbill - The Royal Society for the Protection of Birds
There are no plumage differences between Scottish, common and parrot crossbills, and although the Scottish crossbill is intermediate in size between common and parrot crossbills, it overlaps in size with both.
Thus, the smallest birds (common crossbills) gave types A, B and E, whilst the large billed birds (parrot crossbills) gave type D. Birds with intermediate sized bills, and hence classed as Scottish crossbills, gave type C. It is likely that calls are learned from parents and should remain constant within the species.
If the Scottish crossbill is a biological species, the composition of its neutral (non-functional) DNA should have diverged substantially from that of the common and parrot crossbill.

 NationMaster - Encyclopedia: Loxia
Crossbills breed very early in the year, often in winter months, to take advantage of maximum cone supplies.
Preliminary investigations in Europe and Asia suggest an equal, if not greater, complexity, with several different call types identified; these call types as different from each other as from the named species Scottish and Parrot Crossbills - suggesting either that they are valid species, or else that the Scottish and Parrot may not be.
One suggestion is that limited interbreeding between the different types prevents significant genetic differentiation, and also enables each type to maintain a degree of morphological plasticity, which may be necessary to enable them to feed on different conifers when their preferred food species has a crop failure.

Longfellow has rendered into verse the German legend of the crossbill, which tells that as the Saviour hung upon the cross, a little bird tried to pull out the nails that pierced His hands and feet, thus twisting its beak and staining its feathers with the blood.
At first glance the birds would seem to be hampered by their crossed beaks in getting at the seeds in the pine cones—a superficial criticism when the thoroughness and admirable dexterity of their work are better understood.
There is another species of crossbill, called the White-winged (Loxia leucoptera), that differs from the preceding chiefly in having two white bands across its wings and in being more rare.

They suggest that the crossbills might be included in the genus Carduelis, but given that the adaptations of the crossbills represent a unique evolutionary path, it seems more appropriate to split up the genus Carduelis as it was already done during most of the 20th century.
The species of crossbills are difficult to separate, and care is needed even with Two-barred/Hispaniolan Crossbill, the easiest.
The other species are identified by subtle differences in head shape and bill size, and are the subject of much taxonomic speculation, with some scientists suggesting that the previously held assumption that the Parrot and Scottish Crossbills and possibly the Hispaniolan and Two-barred Crossbill are conspecific.

The parrot crossbill has the largest bill for prizing seeds from pine cones, while the Scottish crossbill —with its intermediate bill — can extract seeds from the cones of a variety of conifers.
The Scottish crossbill, Loxia scotica, was first described as a sub species of the common crossbill in 1904 by a German taxonomist called Ernest Hartert, who noted that the bills of crossbills in highland Scotland were larger than that of common crossbills.
Now that we have shown the Scottish crossbill exists and is endemic, we must focus our conservation efforts in making sure that it not only survives, but flourishes and that Scotland has plenty of the habitat that supports and maintains the population of these birds, of which we should be justly proud.

 Language Log: Scottish dialect genetics
DNA tests had shown the Scottish crossbill, common crossbill and parrot crossbill - which visits from Europe - to be genetically similar.
The Scottish crossbill page on the RSPB website says that it has "[a] 'chup chup' call with a fluty quality", whereas the common crossbill has "[a] loud 'chip chip' call; a warbling, twittering song", whereas the parrot crossbill has "[v]ery similar calls to crossbills, but thought to give a distinctive deep ‘kop-kop’ and ‘choop choop’".
The Appalachian crossbills also showed a pattern of assortative pairing based on acoustic characters, but this observation is trivial because call matching was a prerequisite for identification of birds as mates.
